I believe being really unproductive is fine in small doses. Sometimes you need to just really relax. The problem is when that's how you spend ALL your free time. I mean, have you ever watched tv all day and really felt good about yourself at the end?

Yes and an all nighter to follow! Watched a couple of seasons of Six Feet Under with a buddy of mine years ago, it was fantastic.

No amount of time spent with friends is "really unproductive", it literally keeps us alive. I didn't see a note about it in this article, but I suspect that the no-income people that are happier with their lives are doing low cost entertainment activities with friends.

I like marathon running documentaries. It makes me feel better at the end of them.

It really depends on the quality of what I'm watching. :) Breaking Bad? House of Cards? Been there, done that, didn't regret it at all.

I second that. Also, we don't all have perfect lives. Sometimes an escape (TV, getting high, whatever) is the best use of our time to stay somewhat sane.
