Boxing is one of the best traits to learn. The reason boxing is a good trait to learn is that it teaches control and constraint and when your Starting out it might seen but when your pushed you can never be stopped.
During the first few days in boxing all I could do is get into shape and run. Then Once a week has passed, my teacher showed me how to control my self in the ring. After that he taught me not to use so much energy right away and that was constant. They both took me about a year to learn and I boxed for 4 years.

When I fight now my head doesnt get clouded and I can see every thing that comes at me. Now when I fight its the best feeling in the world. See I could tell you what it feels like, but your going to figure it out yourself.
