Well, just remeber that you can ALWAYS getter better. I find a good way to continously improve is to constantly set goals for yourself, such as planning what you want to get done for the day, such as finish learning a song, or mastering a technique. No one, and I mean no one, can teach you how to play. It's up to your interests and personal studies that makes you good guitarist. Just try to learn something everyday, get a little better every day, play when ever you can, and after a while, that sort of accumulates, then one day you'll find yourself to be a fantastic guitarist. Just remember to look at with a positive attitude, as a hobby instead of a life-consuming activity. Oh, and make sure you have fun with, too.
