Aim to be the best in the world at whatever you do professionally. Even if you miss, you'll probably end up in a pretty good place.

I think as a rough estimate, you should aim to give about 10% of the company to the first 10 employees.

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

The cost of getting an early hire wrong is really high.

If you have several ideas that all seem pretty good, work on the one that you think about, when you're not trying to think about work.

Investors will sort of like write the check and then, despite a lot of promises, don't usually do that much; sometimes they do.

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