I think the point is that mindfulness in your present moment, if done intentionally, can be a beneficial practice. There is value in not constantly seeking dopamine hits and allowing your brain to feel discomfort in doing nothing. It's really up to the individual when they choose to do this, though. I don't personally enjoy doing this in public and when having to do stuff like commute or try to get through a work day. But I can respect that others do.

No, the bus stop is quite boring — and that's fine. My best ideas come when I am bored.
