I concur with Bob; the above is bad advice.
When I decided to learn 3-cushion, there was an older guy in the room, John Mechetta (sp?), who loved to work with those that were serious about the game. He taught me stroke, systems, to replace chalk on the rail face up, and helped replace balls so I can shoot the same shot over & over until I understood it. It wasn't long until I was beating him but I continued to learn from him. John loved the game, was a student of the game & had a wealth of knowledge he was willing to share, I'm just happy I was one of those who decided to listen to him. If you find someone like that, you're lucky. Thanks, John.
A couple years later I found myself in a position to learn from top players who were also great students but w/more talent. This was done by gaining their respect, keeping my eyes & ears open & my mouth shut. Of course, until I had a question. Once I became accepted - then I couldn't keep my mouth shut

.
What I would suggest: is to watch better players (tapes, in person, whatever), but not necessarily take series of "lessons" from those that had/have natural talent and play great, but haven't a clue why or how to verbalize what they do know. Watch what they do & ask questions, but then ask those who DO know if what you believe to be correct, is. The result might be what you want to learn from them, but they might be steering you in the wrong direction to be able to achieve it. Not on purpose & not in all cases, but some just don't know how they do these great things. Some do, though.
To get off on the right foot, it would probably be worth your while to invest in one of these well known classes to make sure you're fundamentals are sound. This is the foundation to your future ability. However, I would do some homework & research the schools, talk to those that have enrolled and find the best fit for you.
These are just my observations and experiences over the years so please take it at that.
Good luck, Dave
