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.

When you are trying to impress people with words, the more you say, the more common you appear, and the less in control. Even if you are saying something banal, it will seem original if you make it vague, open-ended, and sphinxlike. Powerful people impress and intimidate by saying less. The more you say, the more likely you are to say something foolish.

The big difference is, as a man, I can go to a bar at two in the morning and people will be like "He's just a fun guy! That's cool that he can balance all these things." But if you see a person that you know who has two young kids and is a mom, there's no way those perceptions are the same. It's like "Oh, there must be a problem." That's usually what women face.

All the most successful people nowadays who are truly successful and innovative in their field are not people motivated by money.
