Operation: Organization

I'm hoping this is a skill that can be learned.
The goal is to not have my house look like a war-zone the day right after a full-day's cleaning. More kids, less time, and way too much stuff building up - I feel like I have to be cleaning all the time to keep my house presentable, which I don't want to do. There are way too many other important things I want to fit into my day (wrestling with Jackson, squeezing Katelyn, etc. - plus my long list of projects). I don't just need more time to pick things up, but I'm trying to make it more manageable, and a better "system."
So I want tips, advice, what works for you?
