I did a major cleaning out and organized everything in my house. Drove my DH and DD crazy because they had to help me. I bought a labeler and labeled every bin, every box, everything I could so that it would be organized. Now when I need to find something the labels help me find them more quickly.

Clear plastic bins labeled so finding and storing things is easier and they stack great.
Those plastic filing cabinets on wheels with three or more drawers work well.
Different sized small plastic trays in the junk drawers to sort everything.

I have small baskets or containers throughout the house that we use to put things in. When I pick up things, I can just put them in those containers and they are where they need to be. Near our chairs, the bathrooms, DD's toys, etc.
