A crew that only practices the parts it’s good at will look great right up until the part it skipped.

Practice drifts toward whatever feels good, because running the thing you are already strong at is pleasant and running the weak part is not. The trouble is that performance finds the gap you avoided, usually at the worst available moment. A rehearsal that felt great is not evidence of much.

Put the section you have been quietly skipping first next time, while everyone still has energy for it. Spend ten minutes there before anything you enjoy. Do that twice and it stops being your weak part.
