Here's a quick tip that works for everyone, even if you don't have chemical impulses telling you to do more, repeatedly. It helps keep your house a little more sparkly, and it may just help that OCD focus.
Windex is my friend. I'm not being paid to say so. It just is. It's one of my favorite multipurpose cleaners. I have a bottle of it in the bathroom, another in the kitchen, and a third one in the hall closet, so it's always within easy reach.
I have a habit of cleaning the mirror in the bathroom after my morning shower instead of just wiping away the steam with a towel. While I've got the cleaner out, I also spray down either the surface of the sink or the surface of the toilet, alternating days. After squeegeeing the mirror, I use a paper towel to wipe off the surface of whichever surface I've sprayed. That way, with a couple of extra minutes spent each morning, the bathroom stays pretty in between weekend scrubbing, and my clean-focused mind can relax with the image of the constantly shiny, most-used room in the house.
Do you have any quick, daily habits you employ to stay more relaxed in the long run?
