I agree with Ras, expanding your musical horizons can help, also it sounds like a good time to start working on basic harmony, learning how chords relate to each note of the major scale, learning the different chord forms/shapes up the neck, inversions, major, minor, dim, Maj7, min7th, 9ths etc, and learn how they are constructed, what makes a Maj7 a Maj7, etc... Not just memorizing a few shapes, this may not sound real exciting, but you can learn it a bit at a time and use it the rest of your life
