Laura- what you’re saying a bit too theoretic in my opinion, and I’m tempted to say: what comes before? the egg or the chicken? Teaching someone to focus has its limits, people who are not use to “succeeding” in other areas such as school, focussing for them is almost impossible. I have noticed that these students become focussed AS THEY succeed early on in the more basic exercises they must do, otherwise you loose them right away, the more they see positive results the more they believe in repeating a passage and accept your teaching. In other words I don’t believe you get good results through focus first but through initial positive results which will encourage the focus and that could stretched a long way.
