Nearly fifteen years ago, in 2005, we published a Harvard Business Review article with our colleagues which introduced a new approach to personal and professional development: the idea that receiving affirmation is a powerful way for us to grow, particularly when it comes in the form of stories describing moments when we are at our best. In this article we introduced the Reflected Best Self Exercise (RBSE), a tool based on our academic research which is now used by thousands of people globally in corporate trainings, team building, executive leadership programs, and in graduate and undergraduate courses in a variety of disciplines.
