I was like you few months ago. When summer started I decided to stop reading news from online. It was hard at first but quite fast I started seeing the benefits. More focus, more happiness, not being so worried all the time. Now I only read HN (way too often of course :)) and I ordered a newspaper to my home which is published 3 times a week. I get distilled look on whats going on in the world but it’s not eating my focus.
I tried to do this as well... bought a year subscription to the local paper. Unfortunately I live semi-rural and it is written so egregiously its only worth is feeding the firebox each week.
