Set your guitars and banjos on fire and before you write a song smoke a pack of whiskey and it'll all take care of itself.
You can't write if you can't relate.
I just go in the studio and write on the spot and see what comes out.
Sometimes things in life take a few years to digest, and they find their way into the work later on. Sometimes I'm writing about things from eight years ago-they just took a long time to distill and come out in the appropriate way.
