Which Paul Graham essays are essential reading for YC applicants?

If you're applying to YC, reading Paul Graham's (PG) essays is essential homework. He has many articles, but a few are widely considered "bibles" – you'll truly be at a disadvantage if you don't read them. I'll list them for you, ranked by importance:

1. "Do Things That Don't Scale"

   • Why it's a must-read: This essay is arguably the core of the YC philosophy. It tells you that in the early stages of a startup, don't always think about building a fully automated system that can serve millions of users. Instead, you should get your hands dirty, acquire users one by one, talk to them, and provide them with "manual" service. For example, Airbnb's founders initially went door-to-door taking photos for hosts. This helps you truly understand what users need and refine your product. YC interviewers are very likely to ask you what "unscalable" things you did to acquire early users.

2. "How to Get Startup Ideas"

   • Why it's a must-read: Many people think startup ideas come from a "flash of inspiration," but this article will completely change your perspective. PG tells you that the best ideas often come from problems the founders themselves encounter. Don't chase trends; solve a problem that you find genuinely painful, and you'll be the first user of that product, understanding it best.

3. "Startup = Growth"

   • Why it's a must-read: This essay helps you understand the fundamental difference between a startup and a regular small business. A startup's sole goal is "growth" (YC's typical standard is 5-10% weekly growth). Everything should revolve around this goal. After reading this, you'll understand why YC applications place such importance on growth metrics; it establishes a clear standard for you.

4. "The 18 Mistakes That Kill Startups"

   • Why it's a must-read: This is a "pitfall guide." Instead of just learning how to succeed, it's better to first see how others have failed. It lists 18 common ways startups die, such as founder disputes, choosing the wrong market, and spending money too quickly. You can review your project against this list, like checking a medical report, to see if there are any warning signs.

5. "How to Convince Investors"

   • Why it's a must-read: YC applications and interviews are essentially about convincing YC, your first "investor." This article teaches you how to clearly and confidently explain your project. The core is: a good team + a good market + signs of rapid growth. Don't talk about vague concepts; speak with facts and data.

In summary:

If you're really short on time, read "Do Things That Don't Scale" and "How to Get Startup Ideas" repeatedly until their principles are ingrained in your mind. If you have ample time, all five essays above are worth a deep read.

His essays aren't complex business theories; they're more like an experienced elder sharing simple yet incredibly effective wisdom with you. Good luck!
