I wish there was a "Cord Cutting" approach for the internet. It's easy to "Cord Cut" a TV - just don't buy one or don't subscribe to cable. The internet is much harder and, unfortunately, can be just as distracting. Even reading the day's news for an hour or more is rarely that beneficial (at least in my experience).

Unfortunately blocking sites by yourself via hosts doesn't work too well and I have yet to find a productive app that could live up to its promise.
