A good leader inspires people to have confidence in the leader, a great leader inspires people to have confidence in themselves.
You never know the power in having someone who believes in you. Some of the greatest people to ever take a breath on this planet would never be anywhere close to who they are in the history books if it weren't for the motivational leadership that they received from someone in their lives as they were growing up.
"A man who wants to lead the orchestra must turn his back on the crowd." - Max Lucado
In order to be a good leader you have to be willing to do the things in life that a vast majority of people would and will never do. Being a leader requires a person to have passion for people that they may not know very intimately, and confident enough to achieve the goals that they first set out to achieve regardless of how well they truly know someone.
