Yah this is a good post. My coach said the reason I wasn't going to my potential was because he said I had no confidence in myself. People told me my entire life that I don't have enough confidence. So whenever I did pretty much everything I focused and said that "I CAN do this, but I will have to focus it on it." Rather than just thinking I need a miracle to do this kind of attitude. It has improved me as a person and a fighter a lot.
Here's how you get to the point of being relaxed in the ring; training, experience, visualization and positive self-talk.
There are times to stay relaxed, there are times to turn up the heat, with experience you will learn when and how
Alot of people seem to be missunderstand the concept of being relaxed while boxing. All it means is keeping a clear head while fighting and to not think to much. When a boxer loses his cool that is when he loses. You can go all out fighting while keeping a calm clear mind.
