Below I have offered suggestions that have helped many of my own clients tremendously toward excelling in their sport. Direct your focus to what is possible, to what can happen, toward success. Rather than complaining about the weather or criticizing the competition, the mentally trained athlete attends to only those things that he or she can control. You have control over your thoughts, your emotions, your training form, and how you perceive each situation. You have a choice in what you believe about yourself.
Positive energy makes peak performances possible.
Put yourself in a relaxed state through deep abdominal breathing. Then, as vividly as possible, create an image in your mind, of what you want to achieve in your sport. You can produce a replay of one of your best performances in the past. Then use all those positive feelings of self-confidence, energy, and strength in your mental rehearsal of an upcoming event. See yourself doing it right.
