I should probably mention that even though I spent 20h/day working on it, I spent/spend virtually every waking hour either reading/writing/thinking about writing software/business. I don't drink, I don't do drugs, I don't party. I live with my fiancee, and work pretty much every waking hour on something or other. I don't have a blog because it would consume too much time, and I don't interact with other developers because I worry that it will pull me toward the middle of the bell curve. I worry that I may be going insane, but only passively.
