Some thoughts on not wasting your training dollars
Training is not just a monetary investment, it is an investment of your time too. Now do keep in mind that at least 75% of learning takes place after the event. You are not going to learn new things in class, you will be shown new things in class, to really learn them you have to practice them the way they were taught in class.
When I trained with Todd Jarrett in 2008, throughout the weekend Todd kept coming to me, saying "Just try it the way I showed you", and I replied "I'm trying too"
I came home and for 4 weeks shot one box of ammo a day, mentally working on what he had shown me till I got it right, and even 6 years later those old bad habits still show up, but in working on what was shown, I did become a better shooter. It is not like flipping a switch, you have to un-learn things sometimes to make space for new information.
