Earl Weiss
Senior Master
Quick story - People don't like change. 1990 was my first IIC. I took note of 150 things I had to fix. (I had been doing the General's system since 1971 and had some of the most senior instructors in the world). I went back to my club and start talking about all this stuff we needed to fix. . Plenty of people said what they had been doing was good for 10 or more years and did not want to change.
