Louisa Jewell is an expert on Positive Psychology and I saw her speak at a Career Counselling Workshop I attended in 2013. Since I work in the school system, this peaked my interest and I was happy to have the additional reinforcement as I practice this exercise every night before going to bed.
This short video produced by the Canadian Positive Psychology Association demonstrates how one simple exercise, the Three Good Things Exercise, can have an impact not only on student happiness, but faculty and staff too!
