The qualities that constitute leadership seem to be linked with a person's own sense of self worth. For example, a leader is willing to assess a situation and trust in their own ability to act. While the decision may lead to positive results or not, the leader is willing to take a chance because of his or her own confidence in their judgment. Additionally, the leader develops trust in other people, and they trust him/her in return.
A private investigator is a leader, we have to have self confidence (we get rejected a lot), we have to be able to act fast (we might have to run like the wind to stay out of sight), and we need to earn your trust (I am a total stranger you just let in your house, I hope you trust me). Seriously, in this profession we are required to think on our feet because we do not always know what is going to happen on an assignment. We earn our clients trust by producing great results. Whether it is in surveillance work or witness preparation being an investigator requires us to be the best at what we do. It takes initiative and determination. All these are signs of a good leader.
Are you a leader or a follower? I know I am a leader.
