Your question is too general. Could you please send me an e-mail and relate the question to your own aspirations? I will be glad to give you an answer. Now, having said that and on a very general plane, to become more skillful or to improve performance means application of principles allowing for improving first of the general neuro-muscular coordination and then of the specific requirements of a technique or an art. There is not point, unless you have a lot of time to waste, to try again and again and to reapeat over and over the same conditons which are responsible for your difficulty. You need to stop and reconsider completely the means involved and the conditions required for a clear aim. The Alexander Technique offers one way to deal with that.
