“At the end of the day, I write down an 'L' or a 'W,' whether or not the day was a 'Loss' or if it was a 'Win.' It really bothers you to have to write down an 'L.' An 'L' looks like a day I ate a lot of junk food, or I didn't work out when I was supposed to or train when I was supposed to train, or if I felt that I had a bad performance in the ring.”
