I once heard the great South African batsman Barry Richards explain a similar trick he used. When he first goes out to bat, he will tell himself "Look, I am good enough to make 10 runs against any bowling attack in the world" - and he would concentrate on getting those 10 runs only. Once he reaches 10, he'd tell himself the same thing again, and concentrate on the next 10 runs. He made 80 first class centuries in his career.
