Your organizational tips please?

Ok one of my goals in life is to become more organized. It seems like every day I go to work then when I come home I work on the house for hours, and still nothing is ever very organized. We don't have a lot of clutter, but I don't know it's like nothing has a place in my house. I know people say a place for everything and everything in it's place but exactly HOW do you do that? How do you stay organized?
