No one wants to try something for the first time in a pressure situation with an audience. Better to have players be self reliant and recognize what they are doing and be able to correct it themselves. Let them learn from their mistakes without the fear of making mistakes. Decide the one thing that will improve the situation and teach only that. Repetition - Repeat your one instruction until you and the player both seem ready to move.
Nothing improves performance more then doing things over and over.
Don t take your head off but more like Keep your eye on the ball right to the plate . Be Credible - If a player doubts himself, he will doubt you too. Sometimes it is best to let the bad moment slide. Be Brave and Different - Be willing to try new things such as drills, players positions or new strategies. Young players like to challenge themselves.
