Lesson number one: opportunity can be manufactured. Yes, you can wait around for the right set of circumstances to fall into place and then leap into action but you can also create those set of circumstances on your own. In so doing, you manufacture your own opportunities. This has helped me immeasurably.

I think Twitter has brought something totally new to the table.

It's important to credit the brave people that take chances to stand up to regimes. They're the star.

I started out as an artist, and I continue to think of myself as an artist first, and a technologist and entrepreneur after that.

We actually created Twitter and Odeo at the same time. When we realized we didn't really want to be running Odeo anymore we looked around for anyone who wanted to buy Odeo, but not acquire us as a technology. But people aren't as interested in that.

The reason I really started running was for meditative purposes. I would pick some problem to have in my head while running.

We can break news really fast. When an earthquake happens, there are people Twittering about it.
