When youre doing what you love to do, you become resilient. You create a habit of taking chances on yourself. If you do whats expected of you, and things go poorly, you will look to external sources for what to do next, because that will be your habit. You will be standing there frozen. If you are just filling a role, you will be blindsided.

There is no script. Live your life. Soak it all in.

Twitter is a global town square.

I was in Shanghai recently, where Twitter is blocked, and yet there were ads and billboards across town with hashtags on them.

Twitter brings you closer. I mean, we see this over and over again from our users. It brings them closer to the action. It brings them closer to their heroes.

People have Plato's form in their mind of what a leader is, or what a C.E.O. is, and it is a bunch of elements that I really don't conform to at all. I've given this a lot of thought, and I came to the conclusion that I don't care.

The way you build trust with your people is by being forthright and clear with them from day one. You may think people are fooled when you tell them what they want to hear. They are not fooled.
