Amazing anecdote&#x2F;post there.<p>To me, the biggest take-away is: confirm the market before you build. So instead of just coming up with a legitimately good idea and then going to work, set up the marketing material first to measure hits, or talk to people in industry and see if they <i>would</i> pay $x&#x2F;month if such a thing existed.<p>This is even pre-minimum viable product level, this is putting feelers out to see if the MVP is worthwhile.
