I've realized why I don't like watching network television - there's no end to it. It takes willpower and drive to get up from the sofa and say "I've had enough TV." I've seen my daughters regularly get caught in the mind-emptying beam of our Sony big screen. I get caught there just as easily as they do - I just usually make a point of not sitting down in front of the TV unless it's for a recorded movie. Lately, though, I've found myself up late, surfing the channels watching absolutely nothing I can remember the next morning.
What a terrible waste of time. As they say, being aware of your condition is the first step.
