Just doing it is not good enough to get significantly better. You can go through the motions and just do it. Anybody can that, but if you truly want to be the best and achieve your potential you must go beyond just doing it. Just doing it is putting the time; it is mindless work that makes you tired. You have to move beyond just doing it. What you do in training must be done with attention, focus, and precision. Good is the enemy of great just doing it is good, but it is nowhere near good enough. Each training session counts toward earning the right to be the best you can be. So make every training session count, never just do it!
