I don’t think it helps to ask how useful or realistic something is “for people”. It only matters how useful or realistic it is for you. After all, you can’t control people, you can only control you.
If an approach works for you, do it.
On the point about thinking about work all the time: yes, it can be a challenge to turn it off and be more present in the moment, though I’m getting better at it. I have found thus far that embracing it (especially when not with my family) actually frees up more time due to quicker work, and it’s worth the trade-off of being lost in my mind at times.
