Any adult should have used a hammer at least one time. Do you focus on swinging the hammer head or the handle? Are you trying to strike the nail, the tree or paying attention to the swing?
I agree that playing tennis is mostly instinctive and no need to overthink or pay attention to other things other than hitting the ball while playing the game.
However I am seeing fundamental faults in rec players particular the serving motion as most are trying to swing the handle for the serve.
