As a leader, your most important weapon against pessimism (all too prevalent these days) is to transfer your optimism and vision to others. This inspires others to think and act in ways that drive results. Leadership is a transfer of belief -- and great leaders inspire their teams to believe they can succeed. As a leader or manager, you are not just leading and managing people, but you are also leading and managing their beliefs. You must utilize every opportunity available to transfer your optimism!
If you are positive, I am positive you will be a Champion!
