If I don't feel confident about my body I'm not going to sit at home and feel sorry for myself and not do something about it. It's all about taking action and not being lazy. So you do the work whether it's fitness or whatever. It's about getting up motivating yourself and just doing it.
My entire life has been an attempt to get back to the kind of feelings you have on a field. The sense of brotherhood the esprit de corps the focus - there being no past or future just the ball. As trite as it sounds I was happiest playing ball.
