I co-founded a startup with 2 other people and really regret that I didn't quit before the thing kind of imploded after 2 years. I was one of the worst experiences in my life and at the beginning I thought like this guy: oh yeah, life is not tough enough, it needs to get harder so it's challenging and I get somewhere. I wish I had failed fast and left this horrible experience after 3 months.
I'd love to hear more people like you (and me :-) ) Honesty about failures (whatever the reason) lacks so much down here and is so reassuring (when the "whatever" reason is outside oneself)...
Sounds like you have that citation already on hand. Give me that list of many people doing the equivalent of sending people to Mars, changing the auto industry, and building an alternative energy empire.
