As a formerly extremely messy person who now is a neat freak - I feel like a lot of not-cleaning is bc it feels too overwhelming. Set a timer for 20 minutes and do what you can. You’ll be surprised how much you can get done in 20 minutes. Take a 10 min break and repeat if needed. I do a “closing shift” every night where I tidy up so that when I wake up I feel relaxed and not stressed by the mess. I think it’s easy to think of cleaning as a type of punishment or approach it from a place of shame, but trying to reframe it as “I deserve a nice & clean space, my space being tidy feels good” has been really helpful to me. Thinking about when you’re the messiest can help too - for me, when I get ready to go out it quickly approaches disaster, so I’ve been intentionally getting ready half an hour earlier so I have time to put my eight rejected discarded outfits back instead of throwing them on the floor.
Also having a regular hang out with friends at my place encourages me to stay on top of cleaning. Having it nice enough for people to drop in at any moment is heavenly!!! But it shouldn’t just be nice for guests, it should be nice for you too! Again, you deserve it!
