You could always write your rejection letter a letter....huh? I don't think that would make me feel better, though apparently it worked for this college senior getting rejected from non-creative jobs. To apply it to the literary world, it would be something like: "Dear Assanine Literary Rejection: Thank you for the wake up call, for showing me that you are more lame than my novel is. It hurts, but I'm still breathing. Kisses and hugs, W,R"
