Expectations kill the performance

Expectation to make a great performance is what worse can think an athlete. Expectations should be part of selfcontrol that an athlete must have on itself. The only expectation  allowed is to know that you have to stay committed  at your best but when you start you have to put aside any idea of the result and fight in every moment of the race, step by step, shot after shot, inch by inch, second by second. There is nothing beyond this and who is not trained in this goes back.
