I went shooting with a friend the other day. When we got into some training drills I was reminded that old drills still need to be used once in awhile. He set up a drill I have not used in almost 20 years. Once he set this course up and we were shooting it, I realized the value in using drills I used to consider obsolete. There is always room for improvement. A fatal move is thinking you know everything and can’t learn anything new. There is always a way to do something better. If your open minded enough to accept that, then you will gain something from every school you go to. I constantly look for new schools to go to. A few months ago I went to another NRA school. A lot of the stuff they were teaching was years behind the times but I still managed to get something out of the class. Never stop training .
