I haven't read this whole thread, and I don't know if I want to, but I think there is something to be said for having a bit of confidence helping you. When I play basketball, softball, or golf there are days where I feel like I can hit anything. Other days, not so much and I think my performance and results are affected by it. I am no big leaguer, far from it, but if I can feel that from time to time in my backyard, on the course, or on the field, I am sure they can feel it to. Do I believe that they are "seeing it better" as Bill says? No, but I think a little confidence will go a little way. By the way, this wasn't to say that I can detect confidence, concentrating, or trying harder in others because I cannot. This was all based on how I feel when I play.
