Internal memory of good shots

In the game of tennis, instructors always provide tons of corrections for our strokes whether it is follow through, hit the ball earlier, utilize more spin, turn your shoulders, rotate more. The list goes on! However, there is an alternative way as an instructor  that I try to help my students develop good technique and well formed strokes. I always point out immediately when a student has produced a shot that was well formed. After that I tell that student that they should internalize and remember how they hit that shot and try to replicate that shot. Sometimes, it is easier for people to understand what you mean by a shot when you point out when they have done the shot correctly.
