I could pick the first one, that would be so easy for me. I'd write about digital scapbooking, or a mystery, or cooking, or remodeling, or a childrens book about dragons, or.... yes the brain is very busy and giving me ideas at a rapid pace
why aren't I doing all of these books?
I don't know. I think it has something to do with a lack of time. But I am going to particpate in NANOWIMO again this year. ( http://www.nanowrimo.org/ ) and I can't wait. Every spare moment I have will be writing without a care or any worries about editing. If you like to write sign up, it's free and at the end of the month maybe you'll have a book about a dragon that scapbooks on her computer while cooking asparagus in the crookpot or some such silliness too.
