The part about accepting when your focus is shot is good, while I'm not convinced it's gone for the entire day, you can definitely get stuck outside of your "flow state" for a couple hours and you may just have to go do other stuff when it happens.

I think what triggered me was this line - "no early morning notifications - no sudden alert about Putin’s latest military actions."

Unless you're a journalist covering the Ukraine war, you really shouldn't have real time notifications informing you about Putin's military actions, and if you do, that's productivity problem #1.

I'm just saying this guy paints a picture of a constantly interrupted life and from my experience the first line of defense is to reduce the interruptions, with measures that are much more aggressive than the average modern person's.
