One of the most effective ways I've found to keep me on track with my goal of simplifying my life, getting rid of my unneeded possessions, and being happy with what I do have, is to clean or think about cleaning.
Some people get great comfort from the act of cleaning. Me, not so much. It's a chore. It's a task that will never have a beginning or an end. Things will always get dirty and need to be cleaned again. There is no done. It's just done for now. The reward lasts for mere moments. Take dusting for example - by the time you've "finished" dusting an item or area, new dust has settled.
The more possessions you have, the more things there are that need to be cleaned or kept clean. When you look around your space and think about all that needs to be done in order for that space to be clean, does it seem like a daunting task or an easy one? For me, it seems daunting.
I'm a bit of a perfectionist, so when I think about cleaning it's not just a light dusting and vacuuming and wipe up that are on the list. Things must be removed from cupboards. Couch cushions must be upended and vacuumed. Electronics must be moved so the furniture beneath can be dusted. Furniture must be moved so the floors and walls and baseboards can be properly cleaned.
When I think about all that needs to be done with the things I already have in my space, the idea of adding something else to the mix becomes a turnoff. Why add something that will need to be moved, dusted, polished, taken care of? Why add something that I'll have to think about moving, dusting, polishing or taking care of?
Just take a look around at all that you already have in your space that needs to be kept clean when you're thinking about adding to your list of stuff.
Then, do a search online for minimalist interiors and look at some of those spaces and just imagine how easy it is to keep those spaces clean. Imagine if your space was that easy to be kept clean.
