Memory of a Goldfish

Today you said that Strickland had the memory of a goldfish. in other words, he forgets about past fuck-ups and confronts his new task of serving the ball. When the serve doesnt go in, he hops in the passers line and promptly tries to pass a dime. When he doesn't pass the dime he goes to the setter's spot and tries to set a peach and finally he does. This is model volleyball player behaviour, and you say that this peach set happened because Strick had literally forgotten about his recent serving and passing blunders. They'd left his mind. But this repression isn't good enough for those of us who don't also have Strick's boyish enthusiasm, which is the reason I think he set the peach. Aadvising us to "forget your mistakes and concentrate on the new ball" is negative, not in the sense that it is discouraging, but in that it advises us to NOT do something rather than to DO something. When we hear this advice, we automatically remember our last mistake and try not to let it crowd our mind when passing the next ball. Our minds are cluttered. Its like saying 'don't think about your neighbour's wife'...it might or might not have happened before, but after hearing that advice, it certainly will. So whats the solution then? What advice do I think is most effective for the 8 players on our team, in order to produce the best results?
"Approach each ball with confidence. Make it your bitch; Love the pass youre about to make; Love your serve; If you fuck up, try harder and be even more confident; use it as motivation; look forward, always look forward."
