The mirror isn’t a judge. Stop pleading your case to it every morning.

A mirror returns light. Everything else in that moment, the ranking and the verdict, is added on your side of the glass, and the standard being applied keeps moving, so the hearing never ends in your favor. Long sessions in front of it do not produce accuracy, just a closer and closer look at a very small area, which is not how anyone else sees you.

Give it a job and a time limit: check what you came to check, then leave. If the morning starts with an argument at the glass, walk out of it and start the day with something you do rather than something you assess.
