Possessing a creative mind, after all, is something like having a border collie for a pet: It needs to work, or else it will cause you an outrageous amount of trouble. Give your mind a job to do, or else it will find a job to do, and you might not like the job it invents (eating the couch, digging a hole through the living room floor, biting the mailman, etc.). It has taken me years to learn this, but it does seem to be the case that if I am not actively creating something, then I am probably actively destroying something (myself, a relationship, or my own peace of mind).
