I am a man and I own 13 pairs of shoes. They're mostly specialized--water shoes, snow boots, steel toe, fancy shoes, flip flops, running shoes, and several pairs of dress shoes. But when I was backpacking in Europe, I only carried one pair of black Timberland boots with me, which took me from the nightclub to the top of the Tatras to the catacombs of Paris. It's amazing how effortlessly I accumulate junk and how ever…
I’m in a ~450 sq ft studio and having to consciously think about where a new purchase will go cuts down on buying “junk” and makes me a lot quicker to sell or dispose of things that are just taking up space.
Similarly, when I moved to a city with hideously expensive parking, I sold my car when I wasn’t using it enough to justify the expense.
