What is ego? According to Oxford Dictionaries ego is simply “a person’s sense of self-esteem or self-importance”. Do you think you are the best there is? That no one possesses the skills you inherit? And that you are always right and others views are useless?
A real leader does not possess such weak thoughts as he sees the truth transparently and humbly accepts his faults and strengths. He does not make fun of others nor put people down for their weaknesses.
