There is a general thought process among many that great leaders should be Expressive—extroverted, talkative, and charismatic. And many are (great). However, let’s not discount the attributes of the leader who is on the opposite end of the spectrum—mild-mannered and not as talkative. Leaders come in all races, creeds, genders, and personalities.
Whether a person is Expressive (extroverted) or expressive (introverted), that is all personality.
What you really want in your leader is to know if he/she embodies the characteristics of a servant leader, which are: self-ware, trustworthy, humble, caring, visionary, empowering, relational, competent, a good steward, and a community builder.
