To each its own... some people have 5-6 cars, some others are obsessed with watches, last time I counted my mother's shoes she had over 130 pairs, we all have our little obsessions
I can certainly relate to this sentiment.
There are some things I completely try to save cash, and others I completely splurge on.
I don't bat an eyelash on spending $350+ for a pair of jeans, because I know I'll have them and love them for years (still have a 4+ year old pair of Dior Homme jeans).
Same goes w/ watches- though I can't justify a Rolex at the moment, I can appreciate its value and engineering. I wouldn't mind having a few of those, some IWC's, etc later down the road...haha.
and the next purchase I want to dive into are in-ear monitors, around the sub-$300 range. One could be happy w/ $10 Sony headphones, but as somewhat of a freelance audio engineer, it's a passion/job. So it's more or less an investment I guess, not to mention it can hold its value if I needed to sell them.
But again, we al have our vices, ha!
