Focus on what you can do. I get so tired of listening to coaches talk to athletes about they can’t do. Find out what they can do and help them to do it better. By focusing so much on what they can’t do you take away what they can do. I am not saying to completely ignore your weaknesses, by all means work on minimizing them and bring up to the level of your strength, but in the process do not take away the strength. From a coaching perspective tell them what they need to do. Create a learning environment where mistakes are learning opportunities, where they are stepping stones rather obstacles. You learn to get better by pushing the boundaries.
