I think it's very important to have a feedback loop， where you're constantly thinking about what you've done and how you could be doing it better.I think that's the single best piece of advice: constantly think about how you could be doing things better and questioning yourself.
You need to invent things and you need to get them to people. You need to commercialize those inventions. Obviously, the best way we’ve come up with doing that is through companies.
The best response to those who hurt you isn't revenge, but doing your best to have a better life.
Why worry? If you’ve done the very best you can, worry won’t make it any better.
