It could be worth stepping away from the guitar for a little while...a week maybe? Do something else you may have been itching to do that you haven't had time for because of guitar. Take some time to read a book, perhaps a bio on an artist you like. Pursue a genre of music you like but never explored on the guitar. For instance, I like a lot of jazz from the 50's - Miles Davis, John Coltrane, Dave Brubeck, etc. One day I want to explore things like Take 5 and So What on the guitar. It's been done a million times, but it would certainly take me out of my regular patterns with my guitar.
