The future of humanity is going to bifurcate in two directions: Either it's going to become multiplanetary, or it's going to remain confined to one planet and eventually there's going to be an extinction event.

Does the logic connect? What are the range of probably outcomes? You want to figure out what those probabilities are and ideally be the House. It's fine to gamble, as long as you're the House. Also, listen to critical feedback, particularly from friends. Generally they will be thinking it but they won't tell you.

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.

One bit of advice: it is important to view knowledge as sort of a semantic tree - make sure you understand the fundamental principles, ie the trunk and big branches, before you get into the leaves/details or there is nothing for them to hang on to.

I read books and talked to people. I mean that's kind of how one learns anything. There's lots of great books out there & lots of smart people.

I could either watch it happen or be a part of it.

The only reason I was able to accomplish things is the great people willing to work with me. A company is a group of people organized to create a product or service, and that product or service is only as good as the people in the company - and how excited they are about creating it. I do want to recognize a ton of super-talented people. Without them, I would have accomplished very little. I just happen to be the face of the companies.
