Mostly I just over think things.
I really wanted to give myself a challenge and write something in first person. I had a manuscript I was working on a couple years ago that wasn't going anywhere, so I began re-writing it in first person. I couldn't believe when the story just started taking off! Now I can't wait for my SCBWI grant application to be mailed this week so I can really delve into my new character's head.
P.S. Can I just say how drool-worthy I think Hugh Jackman is? I loved him as an X-Man, I loved him as a cowboy, and now I love him as a song-and-dance man.
