Quitting the wrong thing is how you make room for the right one. Not all quitting is losing.

Stopping gets treated as a single act with a single meaning, which it is not. Leaving something that is genuinely wrong for you frees hours, attention and a kind of energy that cannot be created any other way. What makes quitting costly is doing it reflexively whenever things get hard, and that is a different move than a considered exit.

Ask whether you want out because it is difficult or because it is wrong. If it is wrong, name a date, tell someone, and let the space it opens go to one thing you have been unable to fit.
