I was fascinated with jeans, because you can impress your life upon the jeans you wear. The way you sit imprints on the jeans.

I loved couriers. You had this transfer of physical information happening throughout the city and the world. Someone picking up the package, putting it in a bag, going somewhere, taking it out of the bag, giving it to someone else. I thought that was so cool. I wanted to map it, to see that flow on a big screen.

I love cities, and I love city governments in particular. But in politics it would have taken me 8 years from implementing a policy before I would get to see the feedback. With programming I could model the same policies and see the impact immediately. Technology is a far more efficient way to test.

'Luck' is recognizing when the situation encourages build out and execution.

You don't have to start from scratch to do something interesting. You don't have to start from scratch to have a massive impact on the world. You have to have a good idea. You have to convince other people of those good ideas. And you have to push as quickly as possible.

Twitter is the world.

The greatest lesson that I learned in all of this is that you have to start. Start now, start here, and start small. Keep it Simple.
