This is about a single business, that didn't get its investors a profitable outcome? A lot of people would consider getting paid for years to work on something you're passionate about a pretty good way to spend 4 years, let alone with enough saved to go travelling and blow off steam. My old business was a pretty good way to spent 16 years. No investors, no goals, good pay, a perfect environment to stew in and sideline more personal failings. That's what I want to read about - how am I going to fuck up the next business or relationship for the exact same reasons? Can I still do anything about that?
