It's easy to call out the kinds of low-value activities that you don't personally enjoy or partake in. It's a lot harder and more uncomfortable to see them in yourself and have some empathy and not judge others too much for their brain-off vices.
Only when I die and see the big stats board do I want to know how many hours I've wasted on Slay the Spire. And while I love it dearly I can't really delude myself that it's anything other than Candy Crush for nerds.
