Great opportunities almost never fit your schedule.

I get energy from one-on-one conversations most often, and I lose energy from group conversations most often.

Probably the biggest mistake that I made personally is I knew early on that I wanted to go into start-ups and creating kind of software that could help change the lives of millions of people. And basically what I did is I kind of went, okay, well, I need a set of titles and I need a checklist of skills, and I ran through all that, and that wasn't a useless thing, but what I didn't realize, and, you know, and no one gave me the right advice for doing this, is that actually your network, in essentially, is your career.

Social networks do best when they tap into one of the seven deadly sins. Facebook is ego. Zynga is sloth. LinkedIn is greed.

Great opportunities almost never fit your schedule.

All humans are entrepreneurs not because they should start companies but because the will to create is encoded in human DNA.

It's nice to be happy. But the meaning of life is meaning - what's the impact you're having on the world. Suffering to accomplish that is a perfectly fine thing.
