Sure we get frustrated with slow learners... but that is no a reason to fire a student. I once heard a teacher complain about a student... "yeah but he CAN'T dance!!" and our boss jumped on her and replied "YOU are the teacher, of course he can't dance until you teach him!!" One of the best experiences I ever had was learning to play the guitar several years ago. My right hand could pick like a bluegrass champion. My left hand was as slow and stupid as a slug. No matter how many times he told me which cord to hit I just couldn't form my fingers fast enough... meanwhile my right hand was plucking and strumming away with all sorts of crazy hard rhythms! I could see his frustration, in addition to mine. My only solace was repeating to myself "I am doing the best I can right now." I was a very slow learner, but I eventually got to the point where I could play in front of people somewhat decently. So when I have a student that tries hard, really wants it, but just can't make their body do what they want, and it sounds like you, I just repeat to myself "They are doing the best they can right now." Also, I started coaching a couple in my area. They each do pro-am with separate teachers and want to learn to better dance together. Her private teacher said he was amazed and could tell immediately that something had changed in her, right after the first lesson from me. He wanted to know what I was telling her. He asked to take a coaching from me, with her. And confided in me that he had sorta gotten to a point, with her, that made him think that was the best she was ever going to do. He said he was going to have reevaluate his teaching. This is a man that was one of the first pros I ever met 20 some years ago, and I have IMMENSE respect for him. Yet here he was telling me that he didn't know what to do with a simple silver student to get her to progress. I guess we all get to that point sometimes. And every so often it takes some outside info to spark some new life into a student or even a teacher. I hope when I get to a point in my teaching that I kinda give up inside on a student, that some spark shows up and motivates ME forward. Because to the teacher, the frustration isn't really about the student... it is about ourselves!!
