Great TED talk about happiness from Shawn Achor.
He posits that only 25% of job successes are predicted by IQ. We tend to think if we work harder we will be more successful. If we are more successful we will be happier.
Achor argues that every time you have a success you change your goalposts. If happiness is on the opposite side of success your brain never gets there. Our brain he continues, works in the opposite order. Be positive in the present and you perform better with more creativity, energy and productivity.
Good managers understand this and take the time to step back and recognize a team’s success, instill an environment of positivity and add meaning and context to these achievements.
