Here is a key paragraph.
Unlearning is the process of letting go, reframing, and moving away from once-useful mindsets and acquired behaviors. It’s not forgetting, removing, or discarding knowledge or experience; it’s a conscious act of letting go of outdated information and actively taking in new information to inform effective decision-making and action.I have some experience with this from surgeries. In 2012 I had rotator cuff surgery then double knee replacements in June of 2018. In both cases I was unable to play tennis for several months. When I returned to practicing I used this as an opportunity to work on aspects of my game. I think it worked because people commented on how my tennis had improved from the last time they played with me.
