Your margin is my opportunity.

I wanted to project myself forward to age 80 and say, ‘OK, I’m looking back on my life. I want to minimise the number of regrets I have.’ And I knew that when I was 80, I was not going to regret having tried this. I was not going to regret trying to participate in this thing called the Internet that I thought was going to be a really big deal. I knew that if I failed, I wouldn’t regret that. But I knew the one thing I might regret is not ever having tried. I knew that that would haunt me every day.
