Just my personal experience (Score 1)

When I was younger my parents had a rule about tv and video games during the week, they were not allowed except on fridays. As you can guess our weekends were filled with watching tv and playing video games. However as we got older my parents no longer enforced this rule. It was just natural for us to make sure we finished all of our school work. Really it just came down to time management. I guess that those weekends that were full of television and games showed us just how too much of a good thing can stop providing entertainment. Now in my life i still watch tv and play video games but i am able to find differnt ways to entertain myself, and i am very thankful to my parents for this. I am not sure how being able to watch tv during the week would have affected my grades but i am sure that if they ever started to slip my parents would have made sure that i brought them right back up.
