Build quietly until your old limitations become unbelievable.

Announcement is a way of collecting the reward early. Telling people what you are about to become gives you the feeling of having done it, and the pressure of an audience often makes you protect the image rather than do the work. Building without commentary lets you be bad at something long enough to get good. The change then shows up as a fact rather than a claim.

Take the thing you have been describing to people and stop describing it for a month. Put the same energy into sessions nobody sees. Let the next update be something finished rather than something intended.
