Even if you think all those other forms of entertainment are "bad", I'd still ask what's so wrong about being "unproductive" some of the time? I don't think you should seek to be 100% "productive". I think being a cultured person is a perfectly good goal as well.
No, I've learned a lot through it.
> I'd still ask what's so wrong about being "unproductive" some of the time?
Nothing. But TV tends to make me unproductive for more of the time than I want.
edit: And I never just watch TV anyway, I'm always doing something else, like coding or reading HN or looking at code on GitHub.
I do have self-control, at least regarding TV. That's why I don't watch it at all. (I do have a television, it is gathering dust in a cupboard.)
> If I spend 45 minutes watching TV or 45 minutes playing with myself, what's the difference?
It is quite easy -- and millions of people do it -- to spend an entire evening watching TV. I dunno about you, but I have never spent 5 hours non-stop masturbating :-). So the one activity is self-limiting, but the other isn't.
The great thing about TV, unlike playing the guitar, is that you can do other things while watching TV. I can workout, write code, write docs, read HN, write blog entries, write emails, clean the house, cook dinner, put up crown molding, etc... And frankly, I enjoy watching TV more than playing a guitar.
More TV please.
And besides, sitting in front of the TV at least feels like wasting time, and yet here I am on the internet while sitting at my work desk in front of my work computer looking like I'm working!
Like pontificating on Hacker News from a pulpit built of gross generalization? Not everyone who watches TV wastes frightening amounts of time on it. I watch relatively little, almost all of it ends up educating me in some way, and that which does not gives some highly desired chances to shrug off stress and laugh a little.
I'm not immune either, I have been trying to cut down on TV but I still watch maybe four or five hours per week.
