"You will never plow a field by turning it over in your mind" I relate to this so much! For example when I don't do well with a particular kata in class I go over it again and again in my mind. Why did I screw up, again? What am I doing wrong? It can put me in a negative spiral. It is much better when I take a breath and actually do the kata and feel what is going on. Don't get me wrong, thinking about what I want to improve is important, but ultimately I have to actually do the thing I want to improve. So get out there and plow whatever field you need to work on!🙂
