Far too many people judge the quality of their practice by the quality of the shots they hit when they practice. I choose to judge the quality of my practice by how much I succeeded at learning and improving.
I've had great range sessions where I didn't hit a single ball terribly solidly. I've had great range sessions where I didn't hit a ball, with a 6-iron, over 50 yards. I've had great range sessions where I know I'm going to hit a bunch of shanks, and when I do, take that as proof that I'm changing the thing I'm trying to change.
There's no scorecard on the range, and nobody hands out a trophy for a great range session. But if there was a trophy, it should say "Most Improved."
