Don't take it so serious, look at it as a learning experience. Try new things and dont get down on yourself if thing dont go as planned. I remember the first time I took a body shot to the breadbasket(diaphram), I couldnt get up from one knee. Heh I was soo worried about protecting the head...just try and learn from your mistakes. Thats the best thing you can do. What i learned from that? Keep a balanced guard and tighten your abs when you see shots coming.
