Exponential leaders know they must discover their purpose. Without crystal clear purpose, a leader simply cannot architect the future, one of the two jobs of a leader. 

To architect the future, you must have purpose, vision, mission, core values, and a brand ideal. Purpose comes first. It is the quintessential element.

Purpose tells others who you are. It's why you do what you do. Obvious truth coming: no one really cares what you do. They want to know who you are. This is why you do it. This is identity capital. It's the single best investment you can make.
