When I am asked—and I am asked often—why I choose to fight, I am often slow to answer. It is not because I don’t have an answer that I hesitate. It’s because I have too many answers. There are many reasons why I fight; so many that it is difficult to isolate a single one. Fighting has taught me more about myself than I could ever put into words, whether they be spoken or in print. But, sometimes, I can find myself focusing on a specific thing that my career as a fighter has revealed to. And one of them is sometimes quite uncomfortable. I am a clinical quitter. I don’t like pain.
