Positive culture comes from being mindful, and respecting your coworkers, and being empathetic.

I don't think of Twitter as a social network. I think of it as a messaging system that has a lot of social components to it.

I mean, even when it's really simple, there's so much amazing beautiful creativity that can come out of that.

We hired a CSR person at Twitter, years before we hired our first sales person, to make sure we had a culture and impact of doing good.

The most rewarding thing for me has been this affirmation for me that people are basically good and smart, and if you give them a simple tool that allows them to exhibit that behavior, they'll prove it to you every single day.

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

I realized ceativity is a renewable resource. You never run out of good ideas
