The hardest thing in the world is to simplify your life; it’s so easy to make it complex.

Hire extremely independent, intelligent, and passionate people, not necessarily "experts." Maybe three or four of my employees have MBAs, and those guys aren't necessarily at the top of the food chain.

There is a beginning and end to all life - and to all human endeavors. Species evolve and die off. Empires rise, then break apart. Businesses grow, then fold. There are no exceptions. I'm OK with all that. Yet it pains me to bear witness to the sixth great extinction, where we humans are directly responsible for the extirpation of so many wonderful creatures and invaluable indigenous cultures. It saddens me to observe the plight of our own species; we appear to be incapable of solving our problems.

The rules of the game must be constantly updated to keep up with the expanding technology. Otherwise we overkill the classic climbs and delude ourselves into thinking we are better climbers than the pioneers.

The more I make the more I can give away.

But I'm really trying to run this company like it is going to be here a hundred years from now. That's what's important.

To do good, you actually have to do something.
