Build a routine sturdy enough to run on your worst Wednesday, not your best Saturday.

A routine has to survive your bad days, because those are the days it exists for. Plans built on a well-rested Saturday assume energy you will not have on a Wednesday after practice, and when they break most people abandon the whole thing rather than just the ambitious part. A small routine that holds is worth more than a large one that collapses. Durability is the actual feature.

Strip your plan down to what you could manage on your worst day. Twenty minutes, not two hours. Anything extra on a good day counts as a bonus rather than the baseline.
