I think it is very important for me to admit that my first attempts to have my book published have all been rejected.
Don't get me wrong. I still know that my story or a future story will get published, but my initial attempts were not as strong as they could have been. The early chapters lacked something, my query letter wasn't good enough and my mindset about revisions needed to improve.
I have become a much better writer in the past few years, and I now know that the stuff I banged out in 2007 just isn't going to cut it anymore, for me or anyone else.
