You have to have an emotional investment in what you're doing. If you don't love what you're doing, failure is pretty much guaranteed.

We didn't have anything before Twitter that allowed a group of people roaming around a city to communicate instantly, in real time, and in a coordinated way, in a group.

I think we definitely want to focus on the simplicity aspect because it's something that's built into the culture even here at Twitter. Constraints inspire creativity.

I got an idea: people like news why don't we write the news down on a piece of paper, and we'll gas them up and drive them to everyone's house. I mean, if you were going to say that now, it doesn't sound like a great idea, because there are other ways you can distribute the news.

People first. Technology second.

Understand that you dont have all the answers, you just have to start somewhere and keep an open mind.

I haven't been paying attention to politics long enough to have really smart opinions.
