A little dilemma in my training and need advice/insight. I have stayed committed to my bjj coach and training partners for quite some time but seriously considering changing schools due to a bjj learning style or deficiency (depending on the interpretation). Without giving away my schools name, lots of famous highly regarded bjj folks come and go training and coaching at the school and it is great for a lot of the people training there as we get to learn abundant amounts of moves/concepts and train with lots of different people. However, I have come to discover that I am really only able to make progress in any activity if I focus intensely on a single area in a more controlled environment, thus a move 'learned' and practiced once or twice is just in one ear out the other for me. I have tried to get training partners to do and implement drill sessions so we can really study and solidify understanding but I have just been laughed at more or less and generated little if any interest-not just at this one school but other places as well. I really want to stay committed to my coach, so Is it necessary to change my outlook and find mental techniques to readily learn and administer new moves/techniques/concepts, or should I find a school that is more drill centric in light of my learning style?
