Great article, I agree 100%.
When I first started Judo I had no ego and flew through the ranks with fantastic technique, knowledge and a wider range then most beginners.
As time went on I started to develop an ego which my technique deteriorated and I generally became sloppy and didn't care what happened in a fight I would go with it. If someone rolled me, I wouldn't urgently try to avoid it, I would go with it.
It has been a while since this happened but I am only just getting back to form. I am truly disappointed in myself for letting this happen.
