As a writer you know you don't have to deal with a lot of the crap that most people deal with, the political things. Every couple of years when your book comes out then you have to go into these fights with the publisher and the publicist and that's it.

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.

You have the power to think differently about who you are. You have the ability to turn off the critical voice inside of you. That's not you. That's coming from the culture. That's coming from the outside of you. You've internalized the voice of your parents, your teachers, your friends.

Think of it this way: There are two kinds of failure. The first comes from never trying out your ideas because you are afraid, or because you are waiting for the perfect time. This kind of failure you can never learn from, and such timidity will destroy you. The second kind comes from a bold and venturesome spirit. If you fail in this way, the hit that you take to your reputation is greatly outweighed by what you learn. Repeated failure will toughen your spirit and show you with absolute clarity how things must be done.

Understand: people will constantly attack you in life. One of their main weapons will be to instill in you doubts about yourself – your worth, your abilities, your potential. They will often disguise this as their objective opinion, but invariably it has a political purpose – they want to keep you down.

There is almost a touch of condescension in the act of hiring friends that secretly afflicts them. The injury will come out slowly: A little more honesty, flashes of resentment and envy here and there, and before you know it your friendship fades. The more favors and gifts you supply to revive the friendship, the less gratitude you receive.

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