I've just emailed my book off to the Australian agency. I figured that there would be nothing lost in trying to pitch it down under. Nothing ventured - nothing gained as they say.
I'm feeling really good about the amount of actual writing that I have done this week rather than just thinking about it. (I think about it a lot.) My new approach to setting myself targets has definately worked for me. I guess that's what it's all about i.e. finding what works for you.
