Most of the valuable things I have learned from building came from the projects that made it to production. The gap between shipping and not shipping is where the real lessons live.
Most building in public optimises for visibility rather than honesty. The version I find more useful is quieter: making decisions legible, tracking outcomes honestly, and creating a record that is worth something even if no one reads it.
Good enough is not a low bar. It is a precise bar. The threshold moves based on what you are trying to learn next, and getting it right is one of the harder skills in building anything.
