I could not STAND our downstairs hall closet because of the mass of shoes that would accumulate in that spot. I finally bought a bubble crate for each of my daughters. Now, they take off their shoes and throw them in their respective bubble crates, instead of having them thrown all over the floor of the closet.
It's a little thing but I am constantly amazed at how much it it reduces my "clutter" stress.
Don't know if this falls under organizing but I love keeping a container of disinfecting wipes in each bathroom. Just pull one out and run it over the sink and faucet, counter, and toilet seat every morning (or night). Also, make a list of big chores to do every 1st day of the month (wash bathmats and sheets, change air filters, mop, dust ceiling fans, etc).
