I have a bunch of guitars that I acquired over the course of around 20 years (I've been playing longer, but the longest I've had any of the ones I have now is around 20 years). A friend of mine drives a Porsche 718 Boxster S convertible that he bought brand new and cost three times what all those guitars cost combined. Another friend flies overseas multiple times a year, and buys and ships home multiple crates of wine from each trip. Another friend owns at least 5 thousand CDs and another 1-2 thousand LPs on a pretty humble income. Two of my closest friends each have a decent sized main house and a large recreational lake house (and no, they don't ever rent one of them out). An old colleague of mine lives in a small city condo, but spends very nearly as much on restaurants each month as she does on her mortgage. Another old colleague is an absolute stunner of a fashionista, and she spends a ton of her large income (she's also a top flight software engineer in a very lucrative sub-field) on it. This can go on all day, of course.
Meanwhile, I drive a Mazda 3 about 3K miles/year. I hate and avoid air travel except when my work requires it. My wife and I have one moderately sized house, and I shudder at the thought of owning two. I don't spend a lot on fancy meals, and I rarely eat red meat in the first place (which I mention from a cost perspective, not inviting a debate on dietary choices). My wardrobe is simple and small. But...who cares? I have my thing, and they have theirs.
