repeating such lessons of missing product-market fit is worthwhile if only to remind us to keep watching out for these pitfalls. otherwise entrepreneurs may think they no longer matter and make the same mistakes. it's easy to let yourself think you know the market instead of asking it (mistake #1), because marketing research is a hard, ambiguous process, while coding is at least logical and the path (may seem) more obvious (mistake #4). and while you're in this bubble, you need encouragement (mistake #7) to keep you going, especially as a single founder (#6, arguably a mistake). these are all mistakes i've made too. the statement i disagree with is "I'd like to think I got a very cheap MBA along the way." it's unlikely the author got much of that, since in most cases mba's learn much more about running an existing business (accounting, financial projections, etc.) than starting a new business. to be fair, there is, at the core of an mba program, a theme of making decisions under ambiguity and trying to bring as much concrete information into the decision as possible, and the author may be referring more to that aspect. in any case, building your intuition for good decision making requires learning from your mistakes (like other talents).
