I just finished reading "a fighter's heart" by
Sam Sheridan. Sam tells stories of him training
in various martial arts. He starts off training
in Muay Thai, but he also worked on his ground work
in Brazil (where else). He also hangs out with
some dog fighting people.
He also spent some time meditating, but he was bored by that, and only got into it just before he left.
I liked the parts about failure the best. He was sparring in a boxing gym, and the opponent He had a bad injury to his ribs that had stopped him training, but he was better. His opponent hit him in the ribs and he freaked and totally lost the fight. He had a lot of negative dialogue where he started worrying, and he lost focus. This used to happen to me all time. (If I every fought Sam I would train a lot of body shots to the ribs, but maybe he is smart and actually has problems with getting punched in the head. I know that this makes me sound like a bad person, but this is the way fighting works).
He did seem to get injured a lot. I felt sorry for him. He went to train in Brazil, but he injured his shoulder, so he couldn't train.
