Try a video game you used to dominate and you’ll be terrible. Skills fade when you stop. Bad habits loosen the same way.

Nothing you can do stays done on its own. Put a game down for two years and your hands genuinely lose it. The same decay runs on the habits you wish you did not have. They are being kept alive by use, and use is something you control.

Pick one you want gone and simply do not feed it for a fortnight. Not forever, not perfectly, just unfed. It will still be there on day fourteen, but weaker, and easier to say no to than it is now.
