Build something your younger self would recognize as proof you kept going.

There was a version of you who wanted certain things badly and had no idea whether any of it was possible. Building something that version would recognize gives your effort a reference point outside the current comparison game, which is usually rigged against you and always moving.

Think about what you would have been amazed by at sixteen or twenty-five. Some of it you already have and have stopped seeing. Notice that, and let it inform what you are working on next.
