I'm not a pure minimalist in execution, however I do apply certain abstract tenets to my life in order to keep distractions minimal and control what I think is add/adhd.
Tmi, but a few years ago I both left the military and went through a divorce, I sold all of my possessions save for what could fit inside a couple tuff boxes (like floor lockers, maybe 3x1.25' or about so), my ps4, a laptop, my cat; I piled all that into my truck and moved across country to be closer to family. Once I was on my feet again in my own apartment, that was probably the most reduced my life had been. When I initially moved into my apartment I was sleeping on the floor which sucked, so I went to goodwill and bought an old recliner for 12 bucks and was sleeping in that for awhile. Mom complained about my sleeping situation, so a bed came next. That event there kind of catalyzed the slow accumulation of **** again, the quest for "necessities". My brother gave me a tv with a busted pixel he was going to through out, so I had a tv, a bed, some clothes, a recliner, a laptop, and a ps4. Plus whatever other stuff the apt provided.
While I was living sparsely, I picked up art again and with as little distraction I had I was painting all the time. It was really nice, there was some kind of purity of experience in it; something that I feel like the west loses in when participating in a material world. Probably the healthiest I've felt mentally (Less negative thoughts) in a long time. I worked, however once that was done I left it at work, and would just paint until I had to sleep. On weekends, I would paint all day.
That didn't last long, as I acquired things over time to improve "QOL", not only material things but pets, SO.
Material minimalism is an extremely hard thing to accomplish the more living beings that participate in your life unless everyone is on board. And there is a balance that I think can be achieved without sacrificing common sense.
Now, I've limited myself to two general hobbies and only participate in a particular aspect two at a time. One being art, the other being electronics. Then specify further, currently its keyboards and sculpting. Both are fairly disposable(or sell) when/if I need to.
I don't buy clothes, but however I like hats. I tossed a lot of my wardrobe and rotate through <10 items of shirts and pants combined.
My house is fairly empty and unimpressive by normal standards. It's generally fairly (relatively) unkempt because of ADD/too may things going on at once (as I perceive it). So the fight to stay organized is ongoing. However, not being in an apartment is such a win for my sanity. However, I can now sleep through the end of the world thanks to an apt next to a busy intersection.
I apply aspects to my thought processes as well, I don't waste time on thinking about anything other than what I mentioned above. SO/family, pets, hobbies. I very much am into awareness of thought and I've gotten fairly good at it, but again improvement is ongoing. I figure if something will make me better than yesterday, then it's okay. The idea/timing/resource expenditure must align. For example, I want to woodwork. It fits my category of Art, but I don't have money for it, and I am busy doing sculpting. It doesn't meet the requirements, I'm not gonna pursue it at this moment. However, what is free is info so I may look stuff up or do general research so if I ever do start it I'm not trying to do everything at once. I guess my thing is I'm accountable for my time. The stuff I don't do, I write down in a notebook (This is a recent change, so I can let myself forget about it.) More things = less time. I am more frugal with my time than money. The way I figure it is that I have an infinite amount of money, I just don't get it all at once.
I liken my life at an attempt as an ever adapting efficiency machine(meatbag). I spend less time/no time on negligible stuff and and utilitize the extra time to spend on stuff I do give a damn about.
My current "retirement" plan involves a converted van and national parks if they're still there. I should mention that I consider my income bracket to be low middle class on my own, less so with an SO.
