Learning how the racket face works in your hand is 100% tennis. If you can master that concept you can master this sport.
Hit balls one at a time from one side of the court to the other aiming only for the alley.
Do this as a warmup with your hitting partner, make it a game alternating and scoring one point if you make it. Turn it competitive.
You need to give yourself a very specific target to become halfway decent at this sport.
