Tal Ben-Shahar is an author and lecturer who taught popular courses on positive psychology and leadership at Harvard University. He provides six tips for happiness, including giving yourself permission to be human, finding pleasure and meaning in activities, focusing on mindset over status, simplifying your life, exercising mind-body connection, and expressing gratitude. The AmAre formula is presented as a way to measure subjective well-being by assigning weights and grades to factors like awareness, meditation, activity, respect, and eating. The formula is meant to assess strengths and weaknesses to improve happiness rather than predict a perfect score.
