A quick word on systems training. A problem is that many believe that perpetually expanding the number of (unneeded) fundamentals is the way towards mastery, not exploring the diversity of the base fundamentals themselves, in ever-increasingly problematic scenarios that cultivate adaptability and address variability. (Adaptability and organic skillsets are simply not innate in any systems training, nor cultivated with any regularity. They may be added or factored-in, but that’s almost always due to the instructor and his/her methodology)
Most people (the majority) need and crave that system to answer all related questions. (It’s THE major inherent flaw in systems training – over-reliance and universality) Systems, if used at all, should be used as a tool – they should work for you, not you them. You are the great variable in your system, not the other way around. *The other end of the spectrum is the deep-seated belief that a system is needed in any way. (they’re not, but that’s another topic altogether)
That being said, deep-seated belief in a system (or deep-seated belief in anything) can be quite a powerful bloody monster, as we see with the protectiveness, investment, aggression, constant comparisons, and defensiveness on the Interweb. People are often willing to do crazy things for dogmatic adherence to system, similarly as many would for religion, so there’s something to be said for that in and of itself.
