An “instructor” has a responsibility to stay proficient via studying new material to keep current, training with other instructors, and practicing. I won’t ask you to do something I won’t do myself. It’s crucial that I demo each drill in front of everyone and sometimes actively participate in the class alongside the clients. Clients must see me doing what I expect them to do, to lead by example. Doing so is also an opportunity for me to get some practice. Due to my schedule, I don’t get to the range to practice as often as I’d like, so I rely heavily on dry-fire at home and while traveling; shooting in classes serves as a practical self-evaluation.
Every round, every execution of a mechanical skill has purpose and meaning; it tells me something. It doesn’t matter to me what I used to do or what I did yesterday; what matters is what I can do today or tomorrow. I make mistakes, and that’s a good thing.
Training and practice are where we can and should get it wrong. Through repeated study, training and practice, we learn, develop, and maintain a consistent, repeatable, and on-demand level of skill, so if the time comes to do it for real, we are as close to ready as possible.
Yesterday is irrelevant.
What can you do today?
What will you be capable of tomorrow?
Study, train and practice.
