2012 Happiness Challenge: For those of you following the 2012 Happiness Project Challenge, to make 2012 a happier year -- and even if you haven’t officially signed up for the challenge -- welcome! Each week, I post a video about some Pigeon of Discontent raised by a reader. Because, as much as we try to find the Bluebird of Happiness, we're also plagued by the Pigeons of Discontent.
