When was the last time you gave yourself the permission to be human? This is a powerful concept that was first introduced to me by Dr. Tal Ben-Shahar. His course on positive psychology is the most popular class at Harvard University, drawing over 800 students a semester and over 20 teacher's assistants. You never thought you'd see happiness taught at Harvard right? I first heard Tal speak at a positive psychology summit in Washington D.C. He showed a video clip of a baby who was playing and giggling, then all of a sudden crying, then back to giggling and crying again. It was quite a funny feat. Everyone in the crowd was laughing.
