Yea, I think it's huge actually. I've been playing since 12, and to this day I'm nervous when I play a stranger, the nervousness makes me angry, anger fuels me. He is the exact opposite, ZERO EMOTION, great shot, bad shot, you'd never know the difference. He is imitating Fed. He shows frustration against me, but not strangers. Yea he has much more courage than me. When I played against, well hit with Justin Bower, I was all worked up, nervous, feeling like my life was on the line. Justin asked Mick to play, Mick was so cool, I couldn't believe it, he just doesn't get nervous. Great trait, I think you have to have some anxiety to fuel you along, I use anxiety for fuel, but not him.
