I am worthy of happiness.

There's a habit of postponing good things until they feel earned. The day off after the project. The nice thing bought once the debt is cleared. It sounds like discipline and often works more like a fine.

The trouble is that the finish line moves. Whatever standard was set, meeting it tends to reveal a higher one, and the reward quietly gets rescheduled again.

Happiness doesn't come out of a fund that the undeserving deplete. Taking an hour on a Sunday costs nobody anything, and the version of you allowed to have it is the same version doing all the work.
