Some things are wonderful 🙂 . One of them is to find somebody, who shares my convictions. Matt Kuzdub, tennis coach, and a facebook friend, has written a wonderful statement about non-linear pedagogy and the dynamical systems theory and what it means for learning and coaching in tennis. I am working with kids and players, who come for one or two hours in the week to play tennis under the guidance of a professional coach. Matt is working with very ambitioned players and goes with them significantly more intense. But he shares my perception: there is a better way to learn and to coach. And it is evidence based!
