As much as I love the philosophy of Minimalism, it concerns me a bit that its true value is being lost in favor of following a trendy "minimalist" aesthetic.
I often hear people refer to the "one out, one in" strategy of minimalism, but I find this problematic. Sure, minimalism is about having a clear, clean, space to live your life and reducing your attachment to material objects. But it is also about creating less waste, spending less money, and opting out of the consumerist society that dominates our culture.
By practicing the "one in, one out" method of minimalism, buying new and unnecessary things is encouraged, as long as you justify it by giving away/throwing away something else you already possess. Sure, it reduces the clutter in your home, but in the end it just increases the amount of stuff that ends up in a landfill. It doesn't do your wallet any favors, either.
Every purchase you make has an impact, and that impact is there whether or not you donate a blouse to goodwill every time you buy something new. The true spirit of what minimalism is trying to achieve, in my opinion, is satisfaction and gratitude for what we already have.
While I'm all about donating things you no longer use, we shouldn't be using this as a justification to buy more things, especially if you truly want to practice minimalism.
Try making your current belongings last as long as possible, and only buy replacements when you truly need them!
