I firmly believe that we've gotten so used to always-at-hand phones/apps that we can no longer handle spending a few minutes doing "nothing". I see this in my teenager.

The OP may or may not struggle with ADHD, but this is something that IMO isn't ADHD but rather a new pervasive trait across our modern society. Everything must be instant now. Emails and now chats must be replied to instantly. Service/delivery must be as instant as possible. No more waiting, no more "doing nothing". We're all operating at high speed, even during our "down time". And for no good reason -- we're just inflicting this on ourselves.
