There's another discussion currently underway about rejections. I don't mean to criticize its originator; far from it, I think his attitude is healthy and he'll handle the inevitable future rejections well. My question covers writers in general:
Why do we savor our rejections?
Only writers keep files of rejection slips and letters. Every other profession moves on. I was trained as a classical musician, and used to periodically travel to out of town auditions. I don't keep the plane tickets of the auditions I lost. (Which would be all of them.) I learned what I could from the experience, and left it behind. (Out of town auditions involve flying, possibly cross-country, on your own dime to potentially sit in a room with over a hundred other competitors so you can play a five-minute audition, at the end of which the overwhelming majority of particpants will will be told to their faces, "Thank you. Next." That's rejection.)
Why do writers alone have such a fascination with rejection?
