A month is a bit much in my opinion. We shut off the TV, computers, game consoles, etc for a week a little while back. It was no big deal for me at first because I was going to use it to read 1984 again and do some writing. As it worked out though, it kinda turned into a punishment for me because nobody else knew how to entertain themselves (my sons and my wife ... whose idea it was to turn off the 'letronics). Ergo, I ended up not getting 1984 read and did zero writing because I was the source of entertainment.

Long story short. I would suggest a much shorter time and actually have a real game plan going in. Just bailing in will turn into a punishment for someone and serve no real use.
