No, you most certainly didn't. You found the guy who doesn't spend even a tiny fraction of what others do on children, booze, drugs, bars, travel, going out to eat, long trips, interest, hotels, sports events, video games, software, "apps", new cars, parties, education, or junkfood — and hasn't for quite a few decades now.
Which left me way more than enough to build a very nice theater into my home, the entire interior of which I built and wired by hand, after buying the property. Even with a modest income. Also, I bought the property with the specific intent of putting a theater into it - it was an abandoned church, a classic tabula rasa. Just a huge, empty room. And I had mucho help - my SO is awesome, and very much like-minded.
We each have our priorities. Home entertainment and at-home convenience are some of mine, that's all. In fact, almost every optional expenditure I make is in pursuit of a concrete, lasting improvement to my physical circumstance. If you don't have enough left over to do what you dream of by the time you're my age (I started this particular undertaking when I was 50, I'm 60 now), then you're Doing It Wrong.
Up till now, anyway. I don't know what's going to happen to the younger people going forward. Looking a good deal more bleak than it did for me.
