Yep, wipe down the bathroom when you use it. Lock away toys and bring out a box or two each day so they can't dump everything out. Make sure to load the dishwasher after each meal instead of waiting. It just makes it a million times faster. Fold the laundry as it comes out instead of letting it pile into Mt. Laundry then feeling overwhelmed (*cough* my husband needs to listen to this one...). I put a lot of things off limits for a while because I couldn't keep up on them. Bedrooms during the day were off limits, the Lego room was off limits, kids could only be where I gave them permission to be (under my supervision so they couldn't tornado when I was in the other room getting something done).
If you can swing the money, baskets for clutter. Instead of putting that pile of mail or your purse on the counter, throw it in a pretty basket. Looks organized even if it's not.
