If you write Sci-fi or fantasy, or can illustrate those genres, you might be interested in this competition. The prizes are pretty good - starting at $1,000 and going up to $5,000. Sadly I'm not eligible as I'm too professional for them - having sold more than three short stories.
I could enter this one though. They too think three sales mean an author is a professional - but only if the sales are to publications on their qualifying list. I don't count as professional. I rather suspect they wouldn't consider JK Rowling, John Grisham or Alexander McCAll Smith professionals either, so I'm in good company. (Reckon Stephen King is probably barred from entry though) The prize for this one isn't quite so high at £200 but it's not bad.
So the answer to my question is yes ... and no. That proves nothing about me, but does show it's important to read competition rules very carefully.
Here's an old picture of me daydreaming what it would like to be a professional author. I've used it partly as the location makes it relevant, but mainly so I can tell you I've just chucked those jeans out because they're now too baggy!
What would be your definition of a professional writer? I'm not completely sure of mine, but it does involve the person concerned doing some actual writing, so I'm off to do that now.
