Not at all. I can literally stay in my house and be active and fulfilled without spending money, without having to buy anything.
The longest I went without spending money was 26 days. That means buying groceries, fast food, any type of entertainment. Obviously paid my bills but didn't spend or buy anything I didn't need.
The most important thing was no waste. No sitting around getting brain rot from tv, no excess trash and paper, no boxes and packages to throw away, just peace.
Just chilled at home, played chess, read, worked out, made music. Didn't hang out with friends (that required spending money) and go have drinks or buy coffee, and shyt.
That would drive 95% of people crazy.
