Getting to know your musical theory (chords, scales, modes, etc) is important, but keep an open mind to the fact that there are endless things you can do on a guitar.  Learn to be at one with the creation process.  This is important even in learning so-called music theory.  You can learn chords and scales, and start to see that there are many, many ways that it can all relate.  In fact, the more you learn, the more possibilities open up for you as a player and as a writer.  So really tackle and sink your teeth into the knowledge you learn; and don’t make the mistake of thinking that you have learned all there is to know about it.  Rather be open to the fact that there is always more to be revealed to you.  Learn to express this in your playing, and learn to explore the endless possibilities of the guitar and of music.
