As we rise in the ranks, we acquire more power. And with that, people are more likely to want to please us by listening more attentively, agreeing more, and laughing at our jokes. All of these tickle the ego. And when the ego is tickled, it grows.
An inflated ego also corrupts our behavior. When we believe we’re the sole architects of our success, we tend to be ruder, more selfish, and more likely to interrupt others. This is especially true in the face of setbacks and criticism. In this way, an inflated ego prevents us from learning from our mistakes and creates a defensive wall that makes it difficult to appreciate the rich lessons we glean from failure.
The ego always looks for information that confirms what it wants to believe. Basically, a big ego makes us have a strong confirmation bias. Because of this, we lose perspective and end up in a leadership bubble where we only see and hear what we want to. As a result, we lose touch with the people we lead, the culture we are a part of, and ultimately our clients and stakeholders.
Esse último trecho me lembrou um pouco sobre redes sONciais que começam a mostrar apenas o que é do nosso "interesse" com base em nossas navegações anteriores, etc...
