I’ve found that turning off notifications on my phone for all but immediate family to be a wonderful thing.
No notifications from emails/Tw@ter/SMS/phone calls unless its my wife, mother, father or brother.
I now look at my phone significantly less and when I want to, not when other people want my attention. The challenge that remains is convincing my wife to do the same.
Better still the buffer/ring in which the mouse highlighted text is stored is for the most part separate from that of Ctrl-c buffer/ring so you can have two things to paste.
