Hmmm . . . what did everyone tell me when I posted that I was stuck in a rut? They said to start writing songs, develop and finish them. Learn different styles. Alternate tunings and drop tunings.
And you know what? . . . it worked. I started writing new songs and learning other popular ones. Doing wacky stuff with tunings.
I was out of the rut in no time. So best of luck to you dude.
