It's only a little difficult to say no. You've got to believe that the work you're doing is ultimately more useful to the world.

Make every decision—even decisions about whether to expand the business, raise money, or promote someone—according to what's best for your customers.

If I’m not saying ‘Hell Yeah!’ to something, then I say no.

Most people don't know what they're talking about. They move their mouth and say things because they don't want to admit they don't know. Or they think they know, but it's just confabulation and biases. So ignore them unless what they say resonates with some real wisdom inside of you. Assume they're a fool and find out the truth for yourself.

Pay close attention to when you're being the real you & when you're trying to impress an invisible jury.

Success comes from persistently improving and inventing, not from persistently promoting what’s not working.

When you make a business, you get to make a little universe where you control all the laws.
