Life is a gamble. You can get hurt, but people die in plane crashes, lose their arms and legs in car accidents; people die every day. Same with fighters: some die, some get hurt, some go on. You just don't let yourself believe it will happen to you.
I wouldn't want to be ideological about it but I think of it as being the best way to approach this kind of playing. I don't think it works in other music, other kinds of playing.
