Next to my keyboard at home right now I have a list of evidence that I'm a good writer.
1. [person at radio network] referred to me as "our best intern" several years after I'd been there, to someone who didn't know me.
2. [radio god] used one of my stories in a speech as his example of how people should tell stories about science.
3. [wildly successful freelancer and book author] picked one of my stories (ok, the same story) for an anthology.
4. Little Miss likes me, and she's smart.
Under normal circumstances, this might be considered bragging, but I really need this list somewhere where I can see it right now.
UPDATE, 11:58: Ok, I found another one, from an editor I've written for a few times, so please indulge me: "Seriously, though, and not just because I like you personally or want to be nice -- you are one of the most talented writers I've ever worked with." And "...whatever happens, don't let anybody make you think you're a boring writer -- that's crazy talk!"
(Although I realize one could argue that this particular post is boring. Sorry bout that. It's mostly for me. Feel free to place your own requests for affirmation in the comments and I'll tell you why you're awesome. Already did it for Z.Dog, and he didn't even ask.)
