I'm not quite sure what an AA player is. Is it above an A player? First of all to reach A player level one needs to love the game first. Loving the game is the motivation needed to reach a high level. Some love the game and play hours on end but their abilites only let them reach a certain level. Others have the same motivation and can reach a higher level.
In respect to the OP on this thread he himself says that he has the time but not the motivation, then that tells me that he does not have the love of the game that is needed. When we're young we become obsessed with the game to the point that we want to spend all of our waking hours on the pool table. This the love that we can reserve for our game because we have the time to commit to it as opposed to later in life there are other commitments that keep us from putting the time on the table.
The Op admits to being aroung the game most of his life, that tells me that he has played enough to gain knowledge and experience but now wants to get deeper into the game. I believe he can get to the level to be competitive and be satisified with that. Beyond that, it may not be possible unless he has superior abilities and talent than most.
If one started playing at his age with no experience at all I believe one can get to the level of being competitive to A level. Expecting more than that would require him to have inborn excepional skills. At this age there are a lot of tools that are missing that are there when we're young. Not counting the mental parts like drive, desire, hunger for expermintation and the confidence to shoot the shot with no idea that something might go wrong. But the physicasl skills that the young posses like coordination, strength, sight, focus, stamina, and a host of other that are needed to reach a high level of play are not there at later ages.
If one could reach a very high level of play at 40 then why can't it be done starting at 60 or 70 years of age? Not happening. I've been playing for about 60 years and have experienced in the last 20 years the loss of some of my skills and for no other reason other than age. My desire is the same as always but the games is still fading.
My advise is to play as much as you can and be satisfied with what you have and enjoy the game.
I'm 65, but played ALLOT when younger, and you can never play too much is my attitude. Started playing again. In two 128 events I finished, one 13-16 & another 7-8 and 7-8 in another 64 event. It's a start, but matchin' up is waay more fun, and tournaments are Just tournaments. Frank I'm comin' soon, I'll let ya torture me in One hole. :grin-square:
