Reflecting upon something means examining and reviewing one’s actions. Only in this way can something be understood, adjusted and ultimately improved. Reflection lays the foundation for both effective and efficient learning processes. There is no doubt that one has to work on all four success factors. Depending on the type of player and the performance level however, some success factors may be of greater consequence than other ones. Permanent observation of one’s actions in training sessions and matches, a careful analysis thereof and goal-oriented adjustments are constantly required.
