What's the best housekeeping advice you can give me?

In recent years I’ve become, not really a neat freak, but very aware of the state of clutter in my house. I’ve turned into one of those people who finds great joy in vacuuming and stain removal. I feel like I’m constantly picking up after a toddler and husband, and even myself. I try to not let things get out of hand to begin with, but it seems like I’m constantly and forever buried in housework. Sometime I really enjoy it, but if I let the house go a few days, it seems like I’m up to my ears in mess.

Anybody have any tricks up his/her sleeve on how to tackle housework efficiently, without burning out? Got a favorite way to clean something? Know how to get grease stains out of clothing? All cleaning/straightening/storage secrets accepted.
