If I had a bad game and we lost I take it very seriously. I feel if I play a good game that other guys will follow and that will help us win more games. And if I don't, I take it upon myself as being my fault.
Part of that, I think, is being able to tune out folly, as distinguished from recognizing wisdom. You've got whole categories of things you just bat away so your brain isn't cluttered with them. That way, you're better able to pick up a few sensible things to do.
