Jackson is modest, well-educated, has excellent skills, and an insightful analytical mind. All of that training really shows when you speak with him and watch him on the range. His modesty will prevent him from agreeing with me!
I also know a lot of people who have had thousands of hours of professional training (documented) who will never really get the hang of the basics very well. I'm not sure if it's a case of not being receptive to the teaching, or being more interested in the classes themselves rather than what they offer to help you improve over time.
Agreed!
