Knowing where every single dollar of your income goes, and allocating those dollars to only things you highly value, helps a lot. This alone, can yield a minimalistic lifestyle.
I don't hold much value in shoes (other than having one good pair), scarves, slippers. or clothes in general. When people offer me free shit, with rare exception, I politely decline. My clothes closet is tiny and mostly empty.
I rarely ever buy "stuff." Exceptions would include food and replacement parts for things that wear down (e.g bike, car, vacuum, computer). I DO spend my $ on experiences. In full disclosure, I am guilty of accumulating massive amounts of paperwork, that includes tons of mailings, and paper records of virtually everything. 30 years of paperwork does add up no matter how much I try to cull the pile.
