By the way, DomesticImp, I saw your thread about submitting something for the first time. I just casually looked at the thread.
Sending something out for the first time is a little scary. A lot of people are so scared of the prospect of being rejected that they never do so. So, give yourself a little pat on the back for being brave enough to put something you wrote out there.
I kept the first rejection I ever got; a blue postcard from Houghton Mifflin. I'm kind of proud of it; it means I was at least willing to take the risk, knowing full-well what the answer would probably be. A rejection doesn't mean anything in the long run. You hear stories all the time about some famous writer who got rejected thirty times before being accepted. The latest version involves Rowlings and Harry Potter and how many times that story was rejected.
So, congratulations, whether your story is accepted or not.
