Once you learn the techniques of true Leadership and Influence, you will be able to build the confidence it takes to take the lead. The more experience you have acting as a genuine leader, the easier it will be for you. It is never easy to take the lead, as you will need to make decisions and face challenges, but it can become natural and rewarding.
Influence is subtle, yet incredibly powerful. You can order someone to do a task, but you cannot order them to do their best. It simply does not work and usually has the opposite effect. You can influence people to do their best by providing a strong, motivating example in addition to positive reinforcement. Leadership addresses tasks, while influence addresses attitudes and awareness. Influence is the soul of leadership.
