I'm definitely responsible for coming in with some basic chord changes, or ideas. Everybody in the band looks to me to come up with the basic seed, so it's not very productive to come in with nothing.

For someone who's had the level of success I've had, there's been very little critical review of my work, which is pretty fascinating.

I did 13-something years of talking to wrestlers and promoters about why they did certain things and why they booked matches a certain way and what they were thinking and whether they were satisfied with the draw. And I got a lot of insight in the business.

I'd reached a point where there was a direct conflict between what I was trying to be and who I really was.

I wanted to build a tool for my generation: people 20 to 40 who don't want to spend time balancing a checkbook or checking multiple financial institutions' websites. Mint does just that, giving comprehensive, quick insights into a user's finances from their computer, mobile phone and/or tablet.

The thing that the Internet does is it allows labor to move freely across borders in the way that capital does but, traditionally, labor cannot. So the Internet frees workers to be based anywhere and work for employers anywhere.

We see ourselves as the world's digital library. That can be a lot more than books. We do want to expand to other types of content: sheet music, magazines, user-generated content.

I've always been fascinated by the brain. I wrote a lot about brain-tech in my first non-fiction book, 'More Than Human.' So when I decided to write science fiction, that was the technology I gravitated towards.
