You might consider taking a 1 to 1 lesson to help you with setting goals. However you will eventually have to develop your own ablity to pick goals and work thrugh them to completion. Posibly you could have that as one of your goals for your 1 on 1 lessons.

Also, as you continue to develop divergent skills (keeping in mind that you will never get it all down... repeat YOU WILL NEVER GET IT ALL DOWN!!), you should be ever more capable of learning diverse styles. This should ease your efforts to play varrious styles of music. Think how difficult playing a G chord was 2 years ago when you started...

As long as you can contiue to practice you will learn as fast as your body possibly can. In another 2 years you should be able to look back on continually increasing learning ablity. Just don't "should" on yourself. That is not the best way to become the best player you posibly can. When it comes to learning gutar...Patient, persistant practice pays.

People who become good guitarists are people who figure out how enjoy practice... period.
