Graham explains why the most successful startups begin with founders doing things that would never scale to a million users—manual recruiting, personal onboarding, handmade products—and why this unscalable labor is not a bug but a feature of the earliest stage.

Graham argues that the best startup ideas come not from brainstorming but from noticing problems in your own life—particularly problems that seem too small or too obvious for anyone to bother solving. The key insight: live at the intersection of "important" and "overlooked."
