You need to have a culture where people have very high quality standards in everything the company does, but still move quickly.

If someone is difficult to talk to, if someone cannot communicate clearly, it's a real problem in terms of their likelihood to work out.

Don't let the company get distracted or excited about other things. A common mistake is that companies get excited by their own PR.

Every thing at a startup gets modeled after the founders. Whatever the founders do becomes the culture.

The best founders work on things that seem small but they move really quickly. They get things done really quickly.

To get the very best people- they have a lot of great options, and so it can easily take a year to recruit someone.

It's better to have a few users love your product than for a lot of users to sort of like it.
