Unless you want to be metaphorical...
In which case, the small image is, in my mind, the flash competition entries. Have you written yours yet? Only 250 words and a whole month before the closing date. Go HERE
The beautiful and burgeoning cloud below is how my mind is currently feeling about The Exeter Story Prize competition. It's for a story of up to ten thousand words. I have yet to put the details up on the site - soon, promise! The closing date won't be until next April so there's a while to go. By then, the winner of the 2014 Exeter Novel Prize will already have been announced. Could it be you? Go HERE
If you want to give yourself the best chance with any competition, whether it's one of ours or not, then do your homework. So many times during judging do we come across great ideas and talent but the story can't win because of poor execution or a major error resulting of just not knowing! Read the previous winners. Go to a writing class or group. Read a creative writing text book (oh, how can I not give The Creative Writing Student's Handbook a plug here?), or at the very least, get someone else to read your story, if possible someone who writes too or knows more than your nearest and dearest.
If you're reasonably local you might like Friday Writers. Go HERE for more info about the course.
Happy writing and don't forget - you can't win if you don't enter!
