When things have a home, you know where they live and can go find them. My ATM card lives in my wallet. Whenever I take it out for something, it always goes back when it's done. My wallet is usually in one of three places, although when it's not it's visually easy to find. I used to sometimes leave my house without my keys and would lock myself out; or would be afraid I lost my wallet accidentally while I was out. So I bought a chain wallet, and attached my keys to the other end. So now I know if i've got my wallet I've got my keys, and vice-versa. In short, having some systems, reducing or limiting (or simply defining) the homes of things, can go a long way.
