Great article. The last couple weeks I've been really busy with a couple plays I'm in. The time committment has made it impossible for me to get to my thursday, Saturday, and Sunday session for Muay Thai. I have, however been able to make it to Boxing/Sparring on Monday nights. Even though I'm missing some important technique classes I have foudn that through the sparring I'm improving a great deal each week.
I'm a big supporter of this learning and I also agree that sparring (correctly) is the best way to get better.
I'm very careful that if I make mistakes and get beat to stop and go over what I did wrong and also to ask my partners what they're seeing and vice versa.
