"Martin, do you know what mental toughness is? Well, mental toughness is the ability to accept the fact that you're human and that you're going to make mistakes - lots of 'em - all your life. And some of them are gonna hurt people that you love very badly. But you have the guts to accept the fact that you ain't perfect. And you don't let your mistakes crush you and keep you from doing the very best that you can." - Billy Jack
