Self-control isn’t saying no forever. It’s saying “not now” like you mean it.

Permanent bans tend to collapse, because a flat no makes the thing more interesting and turns every day into a test you can fail. Postponement works better. Later today, after this is finished, on Saturday: the want gets acknowledged rather than fought, and the fight is what usually exhausts people. It only works if the later actually arrives, though. A postponement you never honor stops being believed by the part of you doing the wanting.

Take one thing you keep banning yourself from and give it a time instead. Then keep the appointment, because reliability is what makes the delay work at all.
