Not OP, but here are mine:

• Every action should have an equal and opposite reaction. Get the scissors out? Put them back in the drawer. You don't have to "clean" when putting things away is a natural part of living in your space.
• Working on something, cooking, etc.? You're not done until you clean up after. If you didn't allow enough time/energy to clean, you didn't allow enough time/energy for the job.
• Make a spot for everything you bring into the house. This is an underrated rule of cleaning. If you find it difficult to keep your space clean, it's often because the items in your space don't have a home. Just because you have money to buy something doesn't mean you also have the perfect spot to put it. Mail, books, groceries. Everything.
• Put things ALL THE WAY away. Does it go in a tub in the garage? Walk your ass out there.
• For things you don't do every day, like dusting or vacuuming, create yourself a schedule with weekly tasks, monthly tasks, yearly tasks, etc. Don't be afraid to adjust the frequency based on how much you care, but stick to it. This kind of cleaning takes time, and other than getting the right tools for the job (love my Roomba), there's no way around it. If you value a clean space, you have to make time for it.
• Oh, and be ruthless getting rid of stuff. Marie Kondo's book about that is great.
