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.

I think Twitter is the future of communications and Square will be the payment network.

What's interesting about Twitter and the influencers that someone follows - like, say, Shaquille O'Neal - is that they see someone who is using the exact same tools that they have access to, and I think that inspires this hope to be able to really engage with someone like him.

It's empowering to be asked to look at what's possible, not told how to do it.

Pick a movement, pick a revolution and join it.

Making something simple is very difficult.

Revolution looks at the intersection ahead and pushes people to do the right thing.
