Lessons are given on a one to one basis as each individual, being unique, mis-uses themselves in unique and complex ways. And there is the added problem that after years of developing such habits of 'mis-use' the sense of feeling, or sensory appreciation, is usually distorted and unreliable. What you feel is often not what you are actually doing. Individual attention is the safest and most efficient way to overcome this hurdle, guarantee good results and provide privacy and confidentiality. And, as habits have been cultivated over most of a lifetime it is best to take a long term approach to lessons.
Results accumulate with application over time.
