If you take a short survey about your cell phone habits, you can get a free Harvard Business Review magazine subscription. I've never read an issue of this before, but it's described as a magazine for “business leaders” and a subscription costs $80 on Amazon!
I'm not much of a leader though. I can't even get my family to follow me in going caroling. They keep using the same tired, old excuses of “we can't sing” and “it's too cold” or “hey, Goob's had enough eggnog, let's throw him in the snow and see how long he can last.”
