Question for You (Unless You're Naturally Organized – then you can go rearrange your silverware drawer…)

I have an opportunity to work on a project about organization (from the point of view of someone who will never be naturally organized, but has learned how to make it work.)

My question for you is this: If you are not naturally organized, what is your biggest challenge with staying on top of life – is it the house, your family, your schedule. If so, can you tell me what it is?  It would be a big help to my project and it is always great to know that we don't suffer alone…
