What You'll Wish You'd Known
Paul Graham's advice to high schoolers: stop optimizing for college admissions, treat school like a day job, and start doing real work driven by curiosity instead of discipline—because you become an adult when you take responsibility, not when you graduate.

Curiosity turns work into play
The best protection is always to be working on hard problems. Writing novels is hard. Reading novels isn't. Hard means worry: if you're not worrying that something you're making will come out badly, or that you won't be able to understand something you're studying, then it isn't hard enough. There has to be suspense.

TLDR
• Don't plan backward from career goals (premature optimization)—work forward from interesting problems that maximize future options, like a glider pilot staying "upwind"
• High school is a broken system designed to satisfy mindless admissions officers, but rebellion is as stupid as obedience—treat it like a day job and work on real things in your free time
• Great work comes from curiosity turning into narrow, deep interest, not discipline—Shakespeare and Einstein weren't gritting their teeth, they were having fun solving mysteries
• Start now with month-long projects on anything interesting; let unseemly motivations (wanting to be better than others, doing forbidden things) drive you
• The only difference between adults and high schoolers is adults realize they need to get things done—you can make that shift at any age
In Detail
Graham dismantles the standard graduation speech advice of "follow your dreams" as premature optimization—you can't know at 16 what you want to do, and the world changes too fast for fixed plans. Instead, he proposes working forward from promising situations rather than backward from goals. The key metaphor is a glider pilot staying "upwind"—choosing options that maximize future options. Math is upwind of economics because you can go into economics from math, but not vice versa. In practice, this reduces to "work on hard problems" where smart people cluster.
The essay's most radical claim is that high school is fundamentally broken—a fake job that trains you to satisfy admissions officers so mindless that an entire prep school industry exists to game them. But Graham argues rebellion is as stupid as obedience; both let the system define you. The solution is orthogonal: treat school like a day job (do it competently but don't let it define you) and spend your real energy on projects driven by genuine curiosity. He observes that people who do great work have little discipline—they're terrible procrastinators who can't make themselves do boring things. What looks like discipline is just interest taking over once they start. Shakespeare wasn't gritting his teeth trying to write Great Literature; he was having fun.
The practical advice is concrete: pick month-long projects on anything interesting, keep them secret if you want, let unseemly motivations (wanting to be better than others, doing things you're "not supposed to") drive you, and don't worry about whether they're on a path to some official goal. The key insight is that curiosity in ambitious adults isn't the broad, shallow kid version—it morphs into narrow, deep wells. Great questions don't appear suddenly; they congeal through years of experience with material you know intimately. The final permission structure: you become an adult when you decide to take responsibility for your life, and you can do that at any age. Most people realize around 23 that they need to get things done—Graham is letting you in on the secret early.
