I think Janice was on the right track. My teacher tells me all the time, even if I feel nervous and jittery, I should say (not just think) "I am calm".
I hate when in performances, I know the music so well, I am looking at the right keys to play, but for some reason, everything seems to get all jumbled. I think it is because I am thinking about the whole piece rather than what is happening at the given moment.
There is a good chance it is alot like sex --> in "Bing, Bang, BOOM", we need to get through the Bing and the Bang to get the BOOM.

They say all guys think about is the BOOM, but the best will say the Bing and the Bang can also be pretty good.
k, does that analogy of mine make any sense to anyone but me??
