We did Twitter, and Twitter grew so fast, and in 2006 we spun it out into Twitter, Inc.

I started as an artist and I had a side job moving some heavy boxes for a publishing company. They had just gotten a Mac for their art department, the department that creates the book covers. I was kind of showing the art director a thing or two about how to use a Mac. And one day everyone went out to lunch and I jumped on the computer and designed a book jacket and slipped it in the pile to go to the review board in New York. They picked my jacket and when the art director got back to Boston, he wanted to know who designed it and I said, "Me." He was like, "The box guy?"

We realized we weren't really using Odeo, we weren't investing our own time creating podcasts. We were building a tool that was a great idea for some other people. That's a dangerous way to go because if you don't actually use it yourself and love it, then you aren't going to be as fully invested in it from the start. That's what leads you to doing side projects.

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

If you make the opportunity. you'll be the first in the position to take advantage of it.

The thing that excites me, and the thing that excited me about Twitter, is the idea of a flock of birds moving around an object in flight.

Doing startups is all about making mistakes.
