During the middle of my sophomore year of high school, I had to move to Mexico and ended up with no internet or computer for a year and a half. That's how long I had to survive. It at least helped me become a better student during my latter half of sophomore year and all of Junior year. When my mom finally bought me Internet service and a new computer, I was able to rediscover what the internet really was and how much it meant to me.
At this point in time, I think a week or two tops. I have other things I can do such as read, play video games, watch TV shows on my DVR, or even so...GO OUTSIDE AND ENJOY THE FRESH AIR.
