I do like her tip about going ahead and putting on shoes for the day, though. I like to be able to answer the door and step outside to talk to somebody or go to the grocery store without having anything to do besides find my keys. We just got new carpet (and I don't like tracking in dirt from outside the house and having my girl crawl all over it), so we don't wear shoes in the house, but I do make sure I have my socks on or toenails painted and the shoes for the day picked out and ready in the utility room.
The easiest tip I have for keeping it clean (and, amazing, lately, it's been really clean and organized around here) is have places to store things everywhere, have a place chosen for everything, get rid of your clutter, and don't be too picky about what toys go into what storage place. We've got 2 storage ottomans, 3 storage stools, a skinny armoire, a wide armoire, and a set of really pretty boxes in our living room as part of our decor. In our bedroom (DD sleeps in there, and it's her playroom, too, we only live in 4 rooms in our huge house at the moment because we're trying to sell it and I don't want to have to clean too much of it - the living room, kitchen, master bedroom and bath), we have a really classy looking toy box (got it at Ikea), 2 big baskets as nightstands, and 4 under the bed boxes (we all sleep on platform beds). So, there's always a place really handy to put toys. Oh, and the cabinet under my sink is used for mostly stuffed animals, and a few random toys. It literally only takes me about 10 minutes to de-clutter the house. I think I got on DH's nerves a little when I insisted on finding all storage pieces when we redecorated, but he loves it now! We even thought about getting this storage couch and a chair, but since you can't sit on it before you get it, we were really nervous about it not being comfortable:http://www.homereserve.com/
We're planning on moving into an apartment when we move, so if we find we need more storage space, I guess we'll first replace our chair with one of the storage ones.
