> I left San Francisco with no savings, a wife and two kids, for a job in Ann Arbor. 4 years later I founded the company I'm at now (which we sold last year.)

Have you ever written about this period of your life? Having a family and the time/energy/freedom to play the startup game seem so mutually exclusive to me, although I do admit that's mostly my gut speaking out of fear of aging and settling down. I'd really love to hear more about how you managed it all.
