I'm always looking for great songs, and not being much of a songwriter, I depend on great songwriters to send them to me. I go through tons of stuff, and sometimes you just find material that kind of fits and becomes something special.
Sometimes people pick up pet worries that they'll entertain themselves with and that was my big one. So as far as thinking about what that means, one of the definitions of insanity is that you lose your ability to communicate to anybody because your frames of reference have become so different from the rest of the world that you can't communicate anymore.
