## Lessons from Julian Shapiro

Julian Shapiro is a founder and writer who breaks complex systems down into practical handbooks. Best known for building the growth training program Demand Curve, he authors open-source guides on everything from startup acquisition to writing mechanics. Readers use his frameworks to systematically test business ideas and communicate without fluff.

### Part 1: The Writing Process

1. **On the True Purpose of Writing:** "Writing is a laxative for the mind. When you write, your brain cannot stop itself from drawing connections between ideas and exploring their implications." — [*Source: \[Julian.com Writing Guide*](https://www.julian.com/guide/write/intro?ref=antoinebuteau.com)*\]*
2. **On the Writing Equation:** "Writing Quality is defined by a simple formula: Novelty multiplied by Resonance." — [*Source: \[Julian.com Ideas Guide*](https://www.julian.com/guide/write/ideas?ref=antoinebuteau.com)*\]*
3. **On Defining Novelty:** "A novel idea is one that is not just new to the reader, but also significant and not easily intuited. Think of it as new and worthwhile." — [*Source: \[Julian.com Ideas Guide*](https://www.julian.com/guide/write/ideas?ref=antoinebuteau.com)*\]*
4. **On Generating Resonance:** "Resonance is when ideas take root in readers' minds. It is the art of capturing their imaginations and relating to their life experiences so that they feel." — [*Source: \[Julian.com Ideas Guide*](https://www.julian.com/guide/write/ideas?ref=antoinebuteau.com)*\]*
5. **On Using Counter-Narratives:** "You can manufacture novelty by challenging common wisdom. Show people where the accepted status quo is fundamentally broken." — [*Source: \[Julian.com Ideas Guide*](https://www.julian.com/guide/write/ideas?ref=antoinebuteau.com)*\]*
6. **On Elegant Articulation:** "Sometimes novelty is not a new fact, but saying something known so beautifully that others could not phrase it as well." — [*Source: \[Julian.com Ideas Guide*](https://www.julian.com/guide/write/ideas?ref=antoinebuteau.com)*\]*
7. **On Making Readers Feel Seen:** "One of the highest forms of writing is validating the reader's personal, quiet experiences that they have not been able to articulate themselves." — [*Source: \[Julian.com Ideas Guide*](https://www.julian.com/guide/write/ideas?ref=antoinebuteau.com)*\]*
8. **On Starting Without an Idea:** "You do not need a fully formed idea before you sit down. The physical act of writing is what forces you to reason through the topic." — [*Source: \[Julian.com First Drafts*](https://www.julian.com/guide/write/first-drafts?ref=antoinebuteau.com)*\]*
9. **On Being a Proxy:** "Instead of trying to guess what your readers want, be a proxy for them. Selfishly entertain and surprise yourself, and you will entertain and surprise them too." — [*Source: \[Julian.com First Drafts*](https://www.julian.com/guide/write/first-drafts?ref=antoinebuteau.com)*\]*
10. **On Distilling Overwhelming Topics:** "Great non-fiction writers act as filters. They take massive, unstructured topics and distill them into approachable, linear guides." — [*Source: \[Julian.com Handbooks*](https://www.julian.com/?ref=antoinebuteau.com)*\]*

### Part 2: Style and Rewriting

1. **On Loving the Process:** "You will not love writing until you learn to love rewriting. The magic happens when you turn raw thought into polished prose." — [*Source: \[Julian.com Rewriting*](https://www.julian.com/guide/write/rewriting?ref=antoinebuteau.com)*\]*
2. **On the Goal of Editing:** "The primary goal of rewriting is to make the work clear, succinct, and intriguing by removing absolutely everything that does not serve the reader." — [*Source: \[Julian.com Rewriting*](https://www.julian.com/guide/write/rewriting?ref=antoinebuteau.com)*\]*
3. **On Finding Your Voice:** "Voice is not a stylistic choice or a vocabulary exercise. It is simply your unfiltered self captured on paper." — [*Source: \[Julian.com Style*](https://www.julian.com/guide/write/style?ref=antoinebuteau.com)*\]*
4. **On Conversational Tone:** "To find your true voice, write exactly as if you are explaining the concept to a smart friend at a coffee shop." — [*Source: \[Julian.com Style*](https://www.julian.com/guide/write/style?ref=antoinebuteau.com)*\]*
5. **On the Trap of Sounding Smart:** "Avoid the temptation to write smart. Using overly complex words or academic jargon usually obscures weak reasoning." — [*Source: \[Julian.com Style*](https://www.julian.com/guide/write/style?ref=antoinebuteau.com)*\]*
6. **On Concision as a Game:** "Make it a game to see how tight and concise you can make a paragraph without losing its underlying complexity." — [*Source: \[Julian.com Rewriting*](https://www.julian.com/guide/write/rewriting?ref=antoinebuteau.com)*\]*
7. **On the Hook:** "Every piece needs a hook, a peak, and a satisfying ending to maintain the reader's engagement from start to finish." — [*Source: \[Julian.com Writing Guide*](https://www.julian.com/guide/write/intro?ref=antoinebuteau.com)*\]*
8. **On Iterating Toward Mastery:** "Do not just write to build a daily habit. Practice deliberately to iterate toward mastery of the craft." — [*Source: \[Julian.com Practicing*](https://www.julian.com/guide/write/practice?ref=antoinebuteau.com)*\]*
9. **On Removing Fluff:** "Fluff is the enemy of respect. If a sentence does not advance the argument, cut it." — [*Source: \[Julian.com Rewriting*](https://www.julian.com/guide/write/rewriting?ref=antoinebuteau.com)*\]*

### Part 3: Ideation and The Curiosity Faucet

1. **On the Curiosity Faucet:** "To get to the good ideas, you must first let the bad ideas flow out. Think of your creativity as a faucet backed up with murky water." — [*Source: \[Lenny's Newsletter*](https://www.lennysnewsletter.com/?ref=antoinebuteau.com)*\]*
2. **On Resisting Bad Ideas:** "Creators often paralyze themselves by resisting their bad ideas. You have to write them down to get them out of your system." — [*Source: \[Lenny's Newsletter*](https://www.lennysnewsletter.com/?ref=antoinebuteau.com)*\]*
3. **On Filtering for Quality:** "By rapidly cycling through mediocre ideas, your brain reflexively identifies the patterns causing that mediocrity, leading you to novel concepts." — [*Source: \[Lenny's Newsletter*](https://www.lennysnewsletter.com/?ref=antoinebuteau.com)*\]*
4. **On Compulsion Over Consistency:** "Curiosity breeds compulsion, and that is far more important than forced consistency when trying to make work that is fresh and inspired." — [*Source: \[Common Discourse*](https://commondiscourse.xyz/?ref=antoinebuteau.com)*\]*
5. **On Identifying Core Interests:** "Fall so deeply in love with interesting ideas that you literally cannot help but tell the rest of the world about them." — [*Source: \[Julian.com Ideas Guide*](https://www.julian.com/guide/write/ideas?ref=antoinebuteau.com)*\]*
6. **On Sourcing Inspiration:** "Study prolific creators outside your domain. The work ethic of top musicians or novelists holds lessons for software engineers and essayists." — [*Source: \[Lenny's Newsletter*](https://www.lennysnewsletter.com/?ref=antoinebuteau.com)*\]*
7. **On Idea Validation:** "If a concept does not genuinely surprise or entertain you, it will almost certainly bore your audience." — [*Source: \[Julian.com Ideas Guide*](https://www.julian.com/guide/write/ideas?ref=antoinebuteau.com)*\]*
8. **On Connecting the Dots:** "Creativity is not pulling ideas from the ether. It is recognizing unexpected links between existing frameworks." — [*Source: \[Julian.com Guides*](https://www.julian.com/?ref=antoinebuteau.com)*\]*
9. **On Patience in Ideation:** "Do not rush the faucet. The clear water only comes after the rust has been completely flushed out." — [*Source: \[Lenny's Newsletter*](https://www.lennysnewsletter.com/?ref=antoinebuteau.com)*\]*

### Part 4: Startup Growth and Market Pull

1. **On Market Pull:** "Great startups do not force a product into the market. They succeed because they hit a wave of market pull where demand already exists." — [*Source: \[Startup Handbook*](https://www.julian.com/guide/startup/intro?ref=antoinebuteau.com)*\]*
2. **On the Why Now Question:** "If you have bad market timing, it means you launched before the market pull existed. You must be able to explain what recently changed to make this possible." — [*Source: \[Startup Handbook*](https://www.julian.com/guide/startup/intro?ref=antoinebuteau.com)*\]*
3. **On Painkillers vs. Vitamins:** "Avoid building vitamins that are just nice-to-haves. If you are not a painkiller solving a pressing problem, marketing will not save you." — [*Source: \[Startup Handbook*](https://www.julian.com/guide/startup/intro?ref=antoinebuteau.com)*\]*
4. **On Directional Accuracy:** "Do not guess. Buy accuracy by paying domain experts to grill you on what channels actually work for your specific business model." — [*Source: \[Demand Curve Guides*](https://www.julian.com/guide/growth/intro?ref=antoinebuteau.com)*\]*
5. **On Growth as a Competency:** "Growth should not be siloed in a department. It is the intersection of marketing, sales, and product, and must permeate the whole company." — [*Source: \[Demand Curve Guides*](https://www.julian.com/guide/growth/intro?ref=antoinebuteau.com)*\]*
6. **On Competitive Analysis:** "Before inventing a new growth strategy, research how competitors scaled. Read their early interviews and reverse-engineer their proven channels." — [*Source: \[Skio Blog*](https://skio.com/?ref=antoinebuteau.com)*\]*
7. **On Strategic Focus:** "A common mistake is trying to be everything to everyone. Successful startups are laser-focused on being the absolute best at one specific thing." — [*Source: \[Fast Company Interview*](https://www.fastcompany.com/?ref=antoinebuteau.com)*\]*
8. **On No-Brainer Offers:** "Structure your value proposition so it is a no-brainer. Lower friction and provide immediate, undeniable value to the customer." — [*Source: \[Demand Curve Guides*](https://www.julian.com/guide/growth/intro?ref=antoinebuteau.com)*\]*
9. **On Market Timing Triggers:** "Look for shifts in technology, consumer behavior, regulation, or distribution channels. That is where new startup opportunities are born." — [*Source: \[Startup Handbook*](https://www.julian.com/guide/startup/intro?ref=antoinebuteau.com)*\]*
10. **On Avoiding False Starts:** "Many founders waste years pushing a product with no market pull simply because they fell in love with their own solution instead of the user's problem." — [*Source: \[Startup Handbook*](https://www.julian.com/guide/startup/intro?ref=antoinebuteau.com)*\]*

### Part 5: Tactics for Acquisition

1. **On Defining Value Props:** "What bad alternative do people resort to when they lack your product? How is your product better? Turn that into an action statement to form your value prop." — [*Source: \[Glasp Notes*](https://glasp.co/?ref=antoinebuteau.com)*\]*
2. **On Landing Page CTAs:** "Think of your Call to Action as the actionable next step to fulfilling the exact claim you made in your header." — [*Source: \[Glasp Notes*](https://glasp.co/?ref=antoinebuteau.com)*\]*
3. **On Growth Funnels:** "While the growth funnel is often depicted as linear, it is actually a series of interconnected loops." — [*Source: \[Glasp Notes*](https://glasp.co/?ref=antoinebuteau.com)*\]*
4. **On Prioritizing Channels:** "When first designing a funnel, use the ICE framework to prioritize the channels most likely to convert based on historical patterns." — [*Source: \[Skio Blog*](https://skio.com/?ref=antoinebuteau.com)*\]*
5. **On Channel-Market Fit:** "The effectiveness of any acquisition channel depends entirely on your business model. B2C thrives on social channels, while SaaS thrives on product-led growth." — [*Source: \[Demand Curve Guides*](https://www.julian.com/guide/growth/intro?ref=antoinebuteau.com)*\]*
6. **On Self-Liquidating Funnels:** "Aim to build funnels where the acquisition costs are immediately offset by initial customer conversions, allowing you to scale sustainably." — [*Source: \[Demand Curve Guides*](https://www.julian.com/guide/growth/intro?ref=antoinebuteau.com)*\]*
7. **On Hiring for Growth:** "Once the product is built, growth marketers are often the highest-leverage early hires a company can make." — [*Source: \[Startup Handbook*](https://www.julian.com/guide/startup/intro?ref=antoinebuteau.com)*\]*
8. **On Matching Talent to Motion:** "Identify your acquisition motion before hiring. Your growth lead's core competency must match whether you are sales-led, product-led, or paid-led." — [*Source: \[Startup Handbook*](https://www.julian.com/guide/startup/intro?ref=antoinebuteau.com)*\]*
9. **On Small Launches:** "Instead of one massive launch, release products to small, targeted groups to gather iterative feedback and refine the funnel." — [*Source: \[Demand Curve Guides*](https://www.julian.com/guide/growth/intro?ref=antoinebuteau.com)*\]*
10. **On the Reality of Paid Ads:** "Most companies never actually get paid channels to work profitably at scale. They survive on a mix of sales, word of mouth, and product-led growth." — [*Source: \[Glasp Notes*](https://glasp.co/?ref=antoinebuteau.com)*\]*

### Part 6: Building Muscle and Systematizing Fitness

1. **On the Big Three Pillars:** "To build muscle, you must consistently focus on three basic variables: eating enough calories, sleeping enough, and lifting heavy enough weights." — [*Source: \[Building Muscle Guide*](https://www.julian.com/guide/muscle/intro?ref=antoinebuteau.com)*\]*
2. **On the Importance of Prep Week:** "The non-bodybuilding part of fitness is crucial. Take a prep week to handle logistics like buying equipment to remove future excuses." — [*Source: \[Building Muscle Guide*](https://www.julian.com/guide/muscle/intro?ref=antoinebuteau.com)*\]*
3. **On Efficiency Over Complexity:** "Building muscle is not inherently complicated. People fail because they waste time on complex routines instead of executing the basics consistently." — [*Source: \[Building Muscle Guide*](https://www.julian.com/guide/muscle/intro?ref=antoinebuteau.com)*\]*
4. **On Minimalist Routines:** "Your fitness program should fit seamlessly into your lifestyle. A sustainable, minimalist routine always beats an intense program you abandon." — [*Source: \[Building Muscle Guide*](https://www.julian.com/guide/muscle/intro?ref=antoinebuteau.com)*\]*
5. **On Maintenance Modes:** "You do not always have to be growing. It requires significantly less volume to maintain the muscle you have built than it did to acquire it." — [*Source: \[Building Muscle Guide*](https://www.julian.com/guide/muscle/intro?ref=antoinebuteau.com)*\]*
6. **On Debunking Gym Lore:** "Ignore conventional gym lore. Rely on recent sports science research to dictate your volume and recovery periods." — [*Source: \[Smart Blogger*](https://smartblogger.com/?ref=antoinebuteau.com)*\]*
7. **On Execution Tracking:** "Fitness guides fail when they lack accountability. Use spreadsheets and checklists to track every lift and ensure you are actually executing." — [*Source: \[Building Muscle Guide*](https://www.julian.com/guide/muscle/intro?ref=antoinebuteau.com)*\]*
8. **On Psychological Motivation:** "Curating your environment with motivational inputs can artificially maintain the intensity needed to stay consistent during hard weeks." — [*Source: \[Francisco Cortez Blog*](https://franciscortez.com/?ref=antoinebuteau.com)*\]*
9. **On Form Over Ego:** "Lifting heavy is required, but lifting with improper form is a fast track to injuries that will permanently derail your consistency." — [*Source: \[Building Muscle Guide*](https://www.julian.com/guide/muscle/intro?ref=antoinebuteau.com)*\]*

### Part 7: Mental Models and Decision Making

1. **On Defining Mental Models:** "Mental models are frameworks for thinking. They simplify complex things so your brain can reason through them. They are shortcuts through the noise." — [*Source: \[The Product Sherpa*](https://theproductsherpa.com/?ref=antoinebuteau.com)*\]*
2. **On the World as Systems:** "The world is merely a patchwork of systems. By using mental models, you can assess how these systems function and reverse-engineer them." — [*Source: \[Mental Models Guide*](https://www.julian.com/guide/mental-models?ref=antoinebuteau.com)*\]*
3. **On Improving Decisions:** "We often rely on volatile instincts or blind momentum. Models force you to step back and systematically evaluate the variables of a decision." — [*Source: \[Mental Models Guide*](https://www.julian.com/guide/mental-models?ref=antoinebuteau.com)*\]*
4. **On Forcing Functions:** "Apply mental models as forcing functions to hold yourself accountable. They ensure you are being thorough rather than lazy when analyzing a problem." — [*Source: \[Mental Models Guide*](https://www.julian.com/guide/mental-models?ref=antoinebuteau.com)*\]*
5. **On Second-Order Effects:** "Always ask what happens next. The immediate consequence of a decision is rarely as important as the secondary ripple effects." — [*Source: \[Mental Models Guide*](https://www.julian.com/guide/mental-models?ref=antoinebuteau.com)*\]*
6. **On Inversion:** "When trying to achieve a difficult goal, invert the problem. Figure out what would guarantee failure, and systematically avoid those actions." — [*Source: \[Mental Models Guide*](https://www.julian.com/guide/mental-models?ref=antoinebuteau.com)*\]*
7. **On Information Diet:** "The quality of your output is directly correlated with the quality of your inputs. Filter your reading heavily to avoid consuming intellectual junk food." — [*Source: \[Julian.com Guides*](https://www.julian.com/?ref=antoinebuteau.com)*\]*
8. **On Rapid Skill Acquisition:** "Deconstruct complex skills into their smallest component parts. Master the sub-skills individually before trying to perform the whole." — [*Source: \[Mental Models Guide*](https://www.julian.com/guide/mental-models?ref=antoinebuteau.com)*\]*
9. **On Objective Truth:** "Separate your ego from the outcome. Your goal is not to be right, but to find out what is true as quickly as possible." — [*Source: \[Mental Models Guide*](https://www.julian.com/guide/mental-models?ref=antoinebuteau.com)*\]*

### Part 8: Audience Building and Content

1. **On the Bat Signal:** "Writing publicly about your specific interests is a bat signal for your tribe. It is the most efficient way to attract like-minded people." — [*Source: \[Julian.com Writing Guide*](https://www.julian.com/guide/write/intro?ref=antoinebuteau.com)*\]*
2. **On Audience as an Asset:** "An engaged audience is a monetizable asset. Building trust through content pays dividends across any future project you launch." — [*Source: \[Demand Curve Guides*](https://www.julian.com/guide/growth/intro?ref=antoinebuteau.com)*\]*
3. **On Creating Handbooks:** "Do not just write blog posts. Create comprehensive handbooks that serve as definitive resources and live as permanent assets." — [*Source: \[Podscripts*](https://podscripts.co/?ref=antoinebuteau.com)*\]*
4. **On Content Quality:** "Content marketing must be more than just good. It has to directly address deep industry annoyances and establish undeniable credibility." — [*Source: \[Demand Curve Guides*](https://www.julian.com/guide/growth/intro?ref=antoinebuteau.com)*\]*
5. **On Promoting Content:** "When sharing on sites like Hacker News, never ask for upvotes. Title your work to solve a specific pain point that the community already feels." — [*Source: \[Demand Curve Guides*](https://www.julian.com/guide/growth/intro?ref=antoinebuteau.com)*\]*
6. **On Minimalist Aesthetics:** "Use a minimalist design for your content. The aesthetic should never distract from the core goal of deconstructing how things actually work." — [*Source: \[Julian.com Guides*](https://www.julian.com/?ref=antoinebuteau.com)*\]*
7. **On the Value of No Fluff:** "Readers are fatigued by academic jargon and dry theory. Write actionable, zero-fluff guides that they can implement immediately." — [*Source: \[Julian.com Handbooks*](https://www.julian.com/?ref=antoinebuteau.com)*\]*
8. **On Earning Attention:** "You are not entitled to anyone's time. You must earn their attention in the first paragraph and re-earn it with every subsequent sentence." — [*Source: \[Julian.com Style*](https://www.julian.com/guide/write/style?ref=antoinebuteau.com)*\]*
9. **On Meeting Interesting People:** "The most efficient way to meet interesting people is to become someone they already want to meet by doing interesting things and sharing them." — [*Source: \[Julian.com Writing Guide*](https://www.julian.com/guide/write/intro?ref=antoinebuteau.com)*\]*
