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

Don't always worry what your next line is going to be.

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

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.

Believe that if you make courageous choices, and bet on yourself, then you will have an impact.

When I was your age, we didn't have the Internet in our pants. We didn't even have the Internet not in our pants. That's how bad it was. I know I sound like my grandfather right now. We didn't have teeth! There were no questions marks, we just had words! What was I talking about? The Internet...Not only can you not plan the impact you're going to have, you often won't recognize it when you're having it.

If there's ever an example of the importance of making bold bets and focusing on what you love, it's Twitter.
