... you can think about that for everyone you hire: will I bet the future of this company on this single hire? And that's a tough bar.

It's easy to move fast or be obsessed with quality, but the trick is you have to do both at a startup.

More important than starting any startup, is getting to know a lot of potential co-founders.

A third advantage of mission oriented companies, is that people outside the company are more willing to help you.

You cannot create a market that doesn't want to exist.

You want to continue to be run by great products, not process for it's own sake.

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