College. We did a finance case competition and we won, so we thought it'd be a good idea to work together. We wrote/edited a book "Words of the Music Masters" (failed), then we coached a few seminars for college students/recent graduates (failed!) and finally some consulting (sucked). That was 6 years ago. We both took jobs, now we're back.
It's really interesting, we've failed miserably together and starved, we're kinda bulletproof now. Besides, being hungry but not alone made us closer, we're like brothers now. seriously.
