One of the most successful sales people I have ever worked with was most definitely an introvert.
His joy did not come from being able to get clients over the buying line but from actually pulling apart clients situations to really understand the business and its objectives/challenges.
He was consistently the person the team would ask for advice around complex issues.
To understand the strength of introverts, we need to understand why positive thinking is such a necessity for extroverts. While managers see positive thinking as a pragmatic means of improving your focus, bolstering the ability to find solutions rather than dwell on problems, among colleagues it also has high currency as a means of social cohesion. In other words, ‘being positive’ is a signal we send to the group that tells others we are ok, and so are they. It’s an extrovert thing; it’s how we keep each other on-point, on the ball and In The Game.
