Like self-awareness, self-regulation often does not get its due. People who can master their emotions are sometimes seen as cold fish—their considered responses are taken as a lack of passion. People with fiery temperaments are frequently thought of as “classic” leaders—their outbursts are considered hallmarks of charisma and power. But when such people make it to the top, their impulsiveness often works against them. In my research, extreme displays of negative emotion have never emerged as a driver of good leadership.
