I have unsubscribed from many e-mail services I had, and after testing it for about a week, I think I am satisfied with the nearly-zero traffic now.
I am also changing where, when, and how I consume news. —Again. I am going back closer to the Rolf Dobelli thing of concentrating only on the headlines, and only rarely.
I am about to launch into some work which will require that I be good at working without expecting lots of such stimulation as comes from the news and the Internet in general. John M Greer calls it “LESS: Less Energy, Suff, and Stimulation.”
