Winning occurs when the player is in harmony with the idea that his expectation and his performance will be equal. Many players do not win because they lack the mental system to control their performance under stress. Most champions are sure that performance is 90% mental.
Mental management is about maximising the probability of having a consistent mental performance, under pressure and on demand. An outstanding performance is easy, only poor performance is afflicted by frustration and extra effort. When you play really well you are balanced and in harmony with your efforts. If you are to become a winner then your mental management system must be able to balance the three mental components, the conscious mind, the subconscious mind and the self image. All great performances are accomplished subconsciously. We develop skills through repetitions of conscious thought until actions are performed automatically by the subconscious mind. The self-image is the total of your habits and attitudes and can be changed. When the self-image alters, performance will change." -Larry Bassham
