The organizations you lead and the roles you play there, should support and fulfill the purpose for your life, not the other way around. More often than not, we see leaders completely unaware of their calling or purpose other than what their vocational role might dictate.
It is our contention that you are not only created for a particular purpose, but that your Creator desperately wants you to know what it is. The clues are written on your heart, have been evident throughout your life, and are fully embodied in the things that bring you greatest joy, deepest pain, and get you out of bed in the morning.
