I definitely realized that sending out a blast to every agent I could find the first time around was probably a mistake. This time, I'm really researching the agents I want to send to and making sure they seem like a good fit for my book. Whether they agree or not is a different story, but at least I know I'm targeting a more specific audience this time around. I think the first time, I just thought the more people who see it, the better chances I have...and what I realized is that this isn't American Idol where someone is just going to fall in love with what you're doing and say that you're not exactly what they're looking for, but they'll give you a chance anyway because they like you. If they say they're looking for young adult fiction and you send them commercial fiction, you can pretty much expect the Simon Cowell response.
Oh well, I tried. You live and you learn.
So, this time, if I get any Simon Cowells, maybe they're just having a bad day because I sent them what they said they were looking for :)
