5. Practice dry-firing and mirror training.
I read somewhere that it is not advisable to practice in front of a mirror. You get distracted because you get busy admiring how handsome you look.;f You could get a video camera and tape yourself drawing and you can review it later with a friend, at the same time you could also admire how handsome you look.
When I was new to shooting and competition, we video'ed ourselves while competing. We studied our movements and give each other pointers where we need inprovements.
