It's hard to say you have any regrets when you try to see every failure as a learning experience. Having said that, I have in the past also wondered why we don't focus more on other startup failures as a source of learning. The first reason I believe is because most of the epic failures you see come down to more or less the same reasons: founder/management troubles and/or no market. If most failures can be boiled down to that, there isn't a lot to learn from each new failure. However, each time there is a success, it is usually for different reasons and there is a lot to learn. The second reason is why entrepreneurs are usually so forward-focused: you usually do not find a new paths by looking backwards. You learn from your mistakes and you try again. Looking backwards only shows you what others have done, and those are almost always opportunities that have already been realized. You know you are in a promising place as an entrepreneur when the mistakes you make are because you are trying things nobody has ever tried before, as opposed to making the same mistakes others have already made.
