I like rejection.
Not as much as someone saying "This is great, we'll use it!"
But rejection's up there, because most of the time you just get nothing back, and you're wondering "Did they get it? Did it go straight into the spam bin? Did I attach the peg?"
Blah blah blah.
I just got rejected 20 minutes ago by mail, and here it is!
"The Ed says: Sorry not to use. Thanks for sending."
Awesome! That's all I need. Thanks Ed you're alright in my book!
