Showing weakness will encourage your opponents. It inspires them. It encourages them to hit harder. To come faster. But when you don't show any fear, or when you don't show any hurt, you have the opportunity to discourage your opponent. You discourage your enemies. The bottom line is, if you think properly, you don't even have to think about all of that. All you have to think about is that guy across from me is human, and so am I. And he'll never out-work me. He'll never out-think me. And if you can't out-work me, and you can't out-think me, you'll never beat me.
