I took my cable box back to Comcast yesterday after I realized how little there was of value on TV that I can't get otherwise. For instance, Conference and other broadcasts are available on the internet and I have a very extensive movie collection on DVD.
This is quite a bit like going on a diet. I have been tempted at intervals all day to find the remote and browse what might be on TV. It is like when I stopped eating refined carbohydrates 8 years ago. For some time afterwards I was tempted to eat cookies or other goodies. Last year I decided to stop eating any meat unless it was strictly used for seasoning such as bacon crumbles on a tomato sandwich. It took a while for me to stop noticing the sale items in the butcher section.
Remembering those days I realize that it will be awhile before I stop craving the somewhat mindless, very lazy indulgence in TV. Playing a video or using the internet actually takes a lot more physical or mental effort than watching TV with a remote in hand. There are a few things I will miss. But overall I'm certain this is a choice that will have as much benefit for my mental health as my dietary choices have had on my physical health. It is also saving me about 600 dollars a year. ; )
