Sports like football can be extremely complicated but sometimes other sports can be easy- if you are prepared to follow advise. You mentioned I might not have developed in a strict system but ironically, I was one of the few who followed a very simple Gerard Mach approach at the beginning. Others were tarting his stuff up and adding all sorts of crap. The only big difference was that at the early stage I figured that nothing could matter as much as the SE would so everything around it had to be subordinate- especially tempo.
