Right now I only watch about an hour of TV a week, plus about an hour of watching online videos. When I was growing up, I spent about 30 to 40 hours a week watching TV and movies - just like a full time job
. A couple years ago, I stopped watching TV cold turkey just to see what it was like and the effects were amazing. It felt like a mental fog had completely lifted from my brain. I suddenly had a ton of time on my hands, so I took Tae Kwon Do classes and started making money by selling things on eBay and before long I was healthier and had more money than nearly all of my friends.
Giving up TV is something I totally recommend.
