"I could never do it again, building a company that way. I've learned too much. There's a certain value to ignorance, in that you don't know you're trying to do the impossible. It's like walking on a high wire. You can only make it if you concentrate all your attention on getting to the other side. As soon as someone ways, 'What about your safety net?' and you look down, you're dead. Back then, I didn't know what a safety net was, and so I just kept going. Now, I do."
