The point of practicing is to establish what you don’t want:
An editor’s review of the draft of your book will leave you in no doubt that much of it has to go; the rest you can keep.
Too much speed into a bend, and you lose time in your practice lap.
Lose your balance looking for an edge and you might look silly in the warm-up.
But when you find what you do want, that’s the practice you can keep.
