So I am a list addict. I make lists for the grocery store (obviously) which are on the same page right under my list of meals I intend to make that week (so I can cross-reference at the grocery store and see if I forgot anything). I make weekly to-do lists (broken down by day and with little boxes to check off...I know, I know).
On those daily lists of things to do, I include WRITE. It usually gets crossed off, though that doesn't necessarily mean it was a terribly PRODUCTIVE day.
With each successive book, I've tried to become more organized. I have lists of characters and lists of chapter summaries. Then as the writing progresses and editing commences, I start adding lists of things to add, check, or fix. So on the book I'm currently writing (Wherefore Art Thou is the working title simply because the lead character's name is Juliette. I hate coming up with titles...), why oh why didn't I include a list of what exactly each character looks like? I know I planned all that out--it must be buried in the manuscript somewhere, but suddenly I can't remember if our hero's eyes are light or dark. Pretty sure his hair is (if for no other reason than I prefer dark haired men!), but no so much on the eyes.
I think I need to design a database template for each successive book. In it I will be forced to answer questions such as height, coloring, distinguishing marks of all characters. Also immediate family, alive and deceased. That would be helpful. Also, whether or not they are allergic to peanuts. Oh wait, that's the kiddo's field trip form. Still, might come in handy for a character too.
The long and short of it is I don't think you can be too prepared when it comes to details and background material on a char
Great, all I need is one more reason to procrastinate! As if Instagram wasn't enough...
