To Tony Robbins,

Thank you. 
Human needs drive action. The motivation to push limits is often realized when the goal is beyond oneself. Contribution without expecting returns is true fulfillment. Applying meaning to the action allows one to sacrifice comfort and embrace effort. Staring into the eyes of death helps value the moment in hand. The prospect of not delivering on their purpose, leaving unfinished business gives perspective.

I am left with knowing the meaning of my work and the meaning of my life. 
The key to unleashing the power within.

Sincerely,
