Be relentless in your pursuit for expansion.

Nothing is stable in the realm of power, and even closest of friends can be transformed into the worst of enemies.

If you want to be powerful in life you have to enjoy the process. You have to get pleasure out of making the thing that you're making. There has to be that kind of purpose behind it. If your purpose is simply gaining power, if that becomes your end in life then you end up sort of destroying yourself because you lose the sense of detachment that's very necessary.

If you have no enemies, find a way to make them.

A lot of people in college go astray because they choose something that doesn't really, really connect to them. And if it doesn't connect to you, you're not able to put in that 10,000 hours that people talk about. You don't have the focus. And you start off in life on the wrong foot and you never get back.

Most people are perpetually locked in the present. Their decisions are overly influenced by the most immediate event; they easily become emotional and ascribe greater significance to a problem than it should have in reality.

The key to success in any kind of start up is your level of persistence. It's not so much your intellect. The Zuckerburg's, Pages and Brins, that succeed have such a level of belief in what they are doing that they will put up with the kind of crap that most people won't put up with, they are incredibly persistent and resilient.
