They say practice doesn’t make perfect. Okay.
They say it can create mistakes, faults and bad habits. So why do it?
Practice is to repetitions as the sand is to the sea. Take something as simple or as complicated as most motor skills. To improve at them most take repetitions, practice and, guess what, time.
So, the real question in the end about repetitions and practice and time is did the benefits outweigh the drags.
If they do, you’re onto something big and you won’t mind a few drags along the way.
