Did you ever consider that sometimes in life you have to go backwards before you go forwards? My novel currently sits on my hard drive, feeling a little unloved after being rejected by two Agents and I kinda of figured that whilst I'm waiting for the motivation/inclination/time to submit it to further places, I shouldn't stop writing. After all, the more I can get my name out there, the more likely an Agent is to want to act for me. So whilst I was off work ill, I decided to tidy out the spare room, to keep my mind off feeling so ill (there is a logic there somewhere!) and I came across my writing box, crammed full of short stories, features and other writing related things, that I've done in the past. I had a quick look through some of the short stories I wrote and yes they definitely need work and my writing has hopefully improved since then, but there's a few possibilities there, that may just lead somewhere.
So my plan, whilst I decide what my next move is with the novel, is to get re writing these short stories and see if there is a place for them out there. After all there's nothing wrong in delving into your past, to help with your future.
