The first successful meal changes the kitchen from a room into a possibility.

One success changes what a room is for. Before it, a kitchen is where attempts go wrong and the sensible move is to buy something ready made. Afterwards it is somewhere things can be produced, and the difference is not skill but a sense of what is available to you. Capability often arrives as a change of category rather than as gradual improvement.

If you want that in any area, aim for one clear success rather than steady progress. Cook the same simple dish three times until it is reliable instead of trying three different ones. The confidence comes from the repeat.
