Sloppy is not really a lifestyle anyone aspires to. It just happens, usually while we're feeling down or while we're totally engaged with the rest of life.
Sloppy dressing, sloppy piles of unfinished business, sloppy storage of clothes and dishes awaiting washing can drive a more organized partner -- or one more attuned to physical beauty -- up the wall.
If you are that partner, please know that shaming is likely to do more harm than good. Focus on the effort:reward ratio instead.
If a clean desk delights you, the reward side of your ratio is probably higher than your mate's. If you tend to deal with each piece of mail, each note, each project, each sock right away, the effort side is surely lower, too.
To encourage your spouse, either decrease the effort level by setting up storage spaces that are handier and easier to use or increase the reward level by adding a basketball net over or a target in the storage space.
For sloppy clothing, consider gifts of clothes that fit better, go together better, look better, and share the comfort level of sweats or ancient tee shirts. Those will lower the effort level. Raise the reward level with compliments, hugs, or help removing those great-looking clothes at the end of the day.
And if you still need to pick up a few items to make the place look the way you like it, count your blessings while you do it. Think of one great thing about being loved, sharing a home, or being part of a family for each item you remove from where it does not belong.
