i am of the same opinion, crunchycomomma.
clear out what you can control. Your stuff... your area. Go through the kids' clothes, take things to good will or pass the stuff they have outgrown to friends with smaller kids. Books they no longer read give to library. And de-clutter your car. how is that trunk? De-clutter your purse, diaper bag..
I think you'll find you have a lot in your own domain that will benefit by de-cluttering. You will feel so good afterwards btw! Reminds me of exercising... can't stand doing it but so much better afterwards.
you'll be very ready for your treasure map despite your mom's clutter. Frankly, if you don't tell her why you are de-clutterying... just that you want to do it...she might be inspired just watchign you.
