i have my own personal regrets about a start up i cofounded.<p>the idea was great, but we were bootstrapping ourselves in addition to working a full-time job. the other founder was flaky, but they were the business end of it and i didn't need frequent input to do the tech work. the flakiness eventually lead to lengthy delays and two years later, we were beaten to the market by a very similar product that is making plenty of money now.<p>my regret isn't about the high risk or financial loss, its about the substantial time lost on a project that is now, essentially, not even worth putting on a resume. in retrospect, i could've done so much more with that time if i'd have followed some of my other ideas instead.
