> If you can't succeed doing it for 10-20 hours a week as a hobby, it's doubtful working even 80 hours will work. Not necessarily. Speaking for myself, sometimes it's all or nothing. I can't imagine having the same enthusiasm and persistence for a hobby than for a full-time effort, particularly if the latter involved burning a few bridges. I'm not arguing it's rational, or that one should blow one's savings on it, but sometimes full-time is your only choice.
