Ask HN: Where do deadpool founders go?

Background: Fresh out of college, I cofounded a social media startup with another friend. We've been plugging away at it for the last 2 years making all the conceivable mistakes first-time entrepreneurs make. What finally broke the camel's back was actually not money but my realisation one day that we were not capable of executing the plan. There were many reasons for this but to name a few: 1) We were not end users of our product. Dog fooding felt like a chore 2) We caught on to the lean startup/4 steps schools of thought too late and could have saved ourselves a ton of mistakes by just reading the 4 steps 3) Inexperience all through the board from product management to marketing. Bad mentors giving bad advice exacerbated matters So the question is for me is really what next? The context for this question is that I definitely definitely definitely want to be involved in another startup at some point in my life. Call me a masochist but 2 years of microwaveable food and perpetual worry
