Bad form feels natural because you practiced it. Fixing it will feel worse before it feels better.

Practice makes things feel natural regardless of whether they are correct. Years of doing something one way builds a sense of rightness that has nothing to do with whether it works, which is why a genuine correction feels wrong in your hands from the first attempt. Comfort is a measure of familiarity, not quality.

Expect the fixed version to feel worse for a few weeks and do it anyway. Get someone who knows to watch you, because you cannot see your own defaults. The awkward stage is short compared with how long the old way has been running.
