If you are anything at all like me, dealing with clutter is a major task. I need to motivate myself to deal with it, so I've spent some time thinking about exactly why clutter is so bad for us:

• Clutter represents wasted money. Everything you own that you don't use is wasted money. You could have used that money on something you would use, for an experience, for retirement savings, for charity.
• You have to clean around it. Having to move stuff, work around it, etc. makes me far less likely to keep up with regular cleaning, like vacuuming, mopping, and dusting. Less stuff to move makes it easier. Easier means it's more likely I'll do it.
• Clutter wastes resources. If it was made and clutters your space, it uses resources. The time, energy, and natural resources used to make unnecessary things keeps those things from being used in a more productive way.
• Clutter waste time. Have you ever thought about how much time you spend buying, cleaning, maintaining, storing, and sorting your stuff? It's kind of mind-boggling. Less stuff is more time-efficient.
• Clutter clouds the brain. Dealing with all of your stuff and the attendant problems (money, cleaning, maintenance, finding storage space, etc.) takes a lot of mental energy. And it's not particularly fulfilling.
• Living in a clutter space raises your stress level. All you see are tasks you need to complete. A less cluttered environment is more relaxing.

Now, I'm not saying you have to go full on monastic and renounce your personal possessions, but maybe think twice before you buy more. Focus on things you truly need and value and let the rest go.
