As a guitarist, having a good working knowledge of chords and a strong rhytmic feel will always be two of your most valuable assets. The problem is that with alot of beginners they tend to rely on only one particlar style, (because its comfortable). Always dabble in different techniques ( no matter how good your friends tell you you are), because it all depends on what you like, and as the years progress you'll realize how important it is to make music for yourself.
