A good routine is boring on purpose. Excitement is for the results, not the reps.

A routine that stays interesting is usually one you keep redesigning instead of running. Boring is the feature, because the decision is already made and your mood no longer gets a vote. The excitement is supposed to arrive later, in what the repetition builds, and it will not arrive if you keep restarting the system.

Take whatever you are trying to keep up and lock two details in place, the time and the place. Do not improve the plan this week, just run it. If it feels dull by Thursday, that is roughly what it is meant to feel like.
