2 years and you feel bad about not improving with your aim? Get in line. Why do you think there are all of the threads about aiming? Practice is the only way. Never heard a pro talk about a aiming gimmick or secret unless it was in a video. Most use the "ghost ball" method directly or indirectly. They just do it and don't think about it because they have made so many shots. Even they miss, which proves there is no guaranteed system.
A expensive cue isn't a magic feather either.
Get the book "99 Critical Shots" practice them and practice, play, practice, play, get a mentor, watch the pros.
Learn to control the CB.
Take a lesson to learn and develop your stroke.
It is a long journey and there are no short cuts. When you do finally get the "easy" part down you can work on kicks, banks, safeties, strategy.......
Good luck
