Arden and George really good thoughts. Aimee as well. I have tried to explain why BJJ and MMA are so important to me to a lot of people and what Arden and George just said is probably the best way I have ever heard it explained. When I shake hands to start a match my brain shuts off. Completely. I am not thinking about work, family, bills, the economy nothing. I am just a big blob of doingness. I will watch video of my matches and I will see myself doing stuff that I don't even recall. Those are the moments that I absolutely cherish.
I am not quite that way with Olympic lifting. In fact I probably over think the lifts some of the time.
I have read many articles and a couple of books on the being in the zone. I have always related it to that zen state of doingness where no thought is necessary everything just happens.
What we think, or what we know, or what we believe, is in the end, of little consequence. The only thing of consequence is what we do. -John Ruskin
