When I have no internet my entire life improves immensely.
I become more productive, more social, healthier and happier as consequence.
It's basically a drug.
Last time we changed ISPs (5 or so years back), my grades noticably rose by around two levels (C/D to A/B), I got together with my (not current) girlfriend and I picked up coding as a hobby.
Then the net came back and I went back to playing league all day.
