If someone is getting every decision wrong, that's when you need to act, and at that point it'll be painfully aware to everyone.

You want an idea that not many other people are working on, and it's okay if it doesn't sound big at first.

The thing that kills startups at some level, is the founders giving up.

It's better to have no cofounder than to have a bad cofounder, but it's still bad to be a solo founder.

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.

By the way, that's my number one piece of advice if you're going to join a startup: pick a rocket ship.

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