Startups are very hard no matter what you do; you may as well go after a big opportunity.

These all sounded really bad, but they turned out to be good. If they had sounded really good, there would have been too many people working on them.

Good startups usually take 10 years.

You also want to fire people who a) create office politics, and b) who are persistently negative.

Most of the best hires that I've made in my entire life have never done that thing before.

A board member of mine used to say sales fix everything in a startup, and that is really true.

Ideas by themselves are not worth anything, only executing well is what creates value.
