In the summer of 1979 I transferred to the Chicago Mercantile Exchange where I worked as a out-trade clerk/keypuncher/afternoon settlements clerk.  While there I was watching the technical analyst for the partners on the trading floor update his chartbook that he kept for them.  I asked him the difference between a fundamental analyst and a technical analyst. He said "a fundamental analyst can only be proficient analyzing a group of two or three sectors of a commodity or stock sector,but, as a technical analyst you can analyze them all.  I knew I was going to be a technical analyst.
