Product-market fit often has an element of luck, otherwise someone else would have found the opportunity already. So this is really good advice for anyone working on a startup, it's sort of another way of saying the classic YC advice that you should be "building things and talking to customers".
I really like this mental model, one thing I've noticed about my failed startup attempts is that I did a lot of "doing" but not "telling".
I think that’s a slightly different thesis - I think this one is more about ‘lucky breaks’ I.e. Microsoft selling its first basic compiler, vs finding your product market fit.
