My 10-year old son and I are playing a game at the moment: the 30-day Happiness Challenge*. I bought it after he finished his entrance exams for secondary school. A bit of light relief. So each day he plucks a 'happiness challenge' from a little box covered in smiley faces. Two weeks in, he's been smiling at strangers, looking back on old photos and walking barefoot in some rather soggy grass.
My main objective is to keep him on a positive track after the stress of all the exams. Like many of us, he can get lost in the more negative aspects of his day. Apparently, this is a common human trait. "Our view of the world has a fundamental tendency to tilt to the negative," says social psychologist Alison Ledgerwood in a TEDx talk.
