My favorite toy as a kid was Legos. I loved building things, and that's what we're doing with SumZero.

Whether you agree with Julian Assange or what he's doing, there's no question of the impact and scale of WikiLeaks. It's a whole different level.

We are building a company, Gemini, and the ETF, which is another company. I don't know if we're experts, but the goal is not to be an expert but to change the world. Does Richard Branson understand all the physics behind his space craft? I'm not sure.

For better or worse, a lot of people who build things don't want to part ways. They don't have the short exit plan that a lot of the investors have.

One of the cool things about amateur athletics is that, I think, the pursuit is sort of the pursuit of excellence for nothing more than trying to be excellent.

Doing meet ups is one of my favorite things ever.
