There are principles that are commonly accepted as "fundamental" to good play, mostly having to do with simplicity and ease of performance - so the "bible" is already largely written. My purpose is to counter the tendency to simply say "it's different for everybody" when asked for advice about how to play pool. We know more than you seem to acknowledge, and we should say so, especially to beginners.

To me, the only effective pool teachers are those who have turned away from the "what feels good" and "it's different for everybody" type of teaching that I grew up with. Those old teaching methods did not work for me. Although I never gave the game full-time attention, I still never even got to shortstop speed, as I went from one feel good poke-but-no-stroke playing style to another over the course of thirty years of occasional play.
It was Banger Class 101 for me, over and over again, because 'its' different for everybody" and "do what feels good" are poor excuses for effective modern teaching methods, and even worse as learning techniques.
My game finally improved when I began learning from instructors who advocated a set of well-defined fundamentals, to be quickly defined and learned in the classroom or other basic instruction arena, and then developed though heavy practice, instead of muddling along trying this or that during league play.
My teachers currently are people like Tor Lowry and Mark Wilson. Though I am unable to take personal lessons, I am learning a lot from them just following their fairly inexpensive published materials.
There are probably others with similar teaching materials and styles. I am certain I will never, ever again pay attention to a teacher stuck in the ancient school of 'do what feels good" and "it's different for everybody", because although there may be some truth to both those statements, they were never helpful to me.
The instruction that finally got my game in gear came from a set of basic, well defined pool fundamentals presented by advanced players, who gave clear and concise instructions, and insisted on heavy practice to get those basics into muscle memory under many conditions of play.
I applaud guys like Patrick Johnson who understand that many players, beginners and those stuck in a rut especially, need specific instruction, and also need more than a hint here and a tip there followed by the notions of "do what feels good" and "it's different for everyone".
