Believe that if you make courageous choices and bet on yourself and put yourself out there, that you will have an impact, as a result of what you do. And you don't need to know now what that would be or how will it happen because no one ever does.

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.

As you get ready to walk out under the bright lights of the improvisational stage of the rest of your life... be bold. Don't always worry about what your next line is going to be.

Successful businesses measure and count things. I think that's a safe assumption on top of which we can drop the following hypothesis: unsuccessful business either measure nothing, the wrong things, too many things, or finally, they measure the right things but they don't communicate the measurements efficiently.

When you are doing what you love to do, you become resilient.

Twitter is a global town square.

Not only can you not plan the impact you're going to have, you often won't recognize it when you're having it.
