Pfft. Easy as a piece of pie. I have two Tvs in my home and except for weekends when I sit to catch a movie with family, I don't really spend time watching TV. Most evenings, I prefer to read or just watch Netflix on my laptop.
I've been finding it VERY easy to live without TV lately, it's the strangest thing. I think the computer, especially because of YouTube and Google is starting to win when it comes to grabbing my attention. The only time I turn to the TV is when I really feel like watching a movie I haven't seen in a while, so I order it (hopefully) for free. All the other times, I'm either browsing items on Amazon (but first Googling them) or watching YouTube videos.
it's hard to even imagine not been able to watch tv for even a week. but yes it's possible when you are all grown up and have other things that keep you occupied.
