I can offer advise. Just KNOW that you are going to crash, and crash a lot. It is the nature of the beast. I am a retired peace officer and I teach martial arts professionally. I tell my students that when they go into battle, expect to get hit, kicked, bitten, shot, stabbed, etc. So when it does happen to them they won't be surprised. They are much calmer, and concentrate on learning instead of worrying about being hurt. After you accept the inevetible, the rest is easy.
