That culture of frugality and discipline is really important for the Y Combinator mindset.

Insight: There's something counterintuitive about this idea, especially in our moment of inflated startup valuations and founder celebrity. You'd think that to build something world-changing, you'd need unlimited resources and permission to spend lavishly. But Altman's point cuts against that. A scrappy mindset—where every dollar has to earn its place, where you build with constraints rather than around them—actually forces clearer thinking. This shows up everywhere, not just startups. A writer working in a coffee shop with a notebook often produces better work than one with a $3,000 standing desk. A team with a tight budget learns to collaborate tightly and question assumptions. Constraints kill the noise. When you can't throw money at a problem, you have to throw creativity at it instead. The deeper insight is about how frugality breeds respect for what you're building. If you're willing to spend wildly on things that don't matter, you probably haven't thought hard about what does. Discipline—in how you spend time, resources, attention—is less about deprivation and more about clarifying what actually matters. It's the opposite of settling. It's the path to building something that lasts.
