Great message, well explained. It was also timely as I've just been reflecting on how this discipline is required for much longer than one initially imagines.

Great message, well explained. It was also timely as I've just been reflecting on how this discipline is required for much longer than one initially imagines. I've become pretty ruthless at remembering that an idea is nothing more than a hypothesis. I'm completely sold to the fact that during the first couple of months you assume nothing and test everything. I now find that the silent danger comes when I feel a whiff of interest from the market and start to lull myself into thinking that I've validated my idea. Without even realising it I start feeling free to indulge a little more deeply in the "things I find interesting" (features / scaling / design). The truth of course is that the process of market-fitting isn't complete until a product is selling repeatedly. Even then it's only selling to a segment of a market and a fraction of the channels you'll ultimately use. The ruthless focus on "what matters" and not "what's interesting" is a large part of what I think separates the entrepreneur from the hobbyist.
