Recognising the effect of power on executives as they rise through the ranks is more than just being 'emotionally aware.' Power takes many forms, and recognising how you react to it, and cope with it, is a good start to being able to manage the effect of it on yourself, and the impact of it on others and on the culture of the organisation.
A lot of people get to the top without doing a lot of personal introspection or growth. While they seem to have learned emotional intelligence along the way, it’s often fairly superficial. For example, they may have learned how to manage relationships, but they never truly learned to empathize or read people fully or accurately. They may be able to decipher motives and needs, but only enough to get things done. When it comes to self-management, a lot of leaders learn to manage the outward expression of emotion but don’t have a clue about how to deal with deep-seated emotions such as insecurity or how they feel about power and authority. As for self-awareness, that’s where I see the biggest gap. Partly because personal reflection has never been something we do in business; it just hasn’t been deemed necessary.
