In YC's case, the number one cause of early death for startups is cofounder blowups.

Cofounder relationships are among the most important in the entire company.

Because it's one of these sort of connections between nodes- every pair of people adds communication overhead.

If you can just learn to think about the market first, you will have a big leg up on most people starting startups.

Startups are not the best choice for work-life balance, and that's sort of just the sad reality.

If you're not in college and you don't know a cofounder, the next best thing I think is to go work at an interesting company.

You're either not hiring at all or it's probably your single biggest block of time.
