The disease of me, Our ego and getting in our own way.. It happens to us all. 

It happens to the best minds on the planet, but for every flawed trait we have as humans, we also have the ability to practice the opposite of it. To control how we react and how we approach situations to remove our egos.

This is an amazing man who I'd never heard of until I read Ryan Holliday's "Ego is the Enemy."

General George Marshall remains (after George Washington) the most respected soldier in American history. Yet he never had command of troops in battle, which is normally the customary path to greatness for a military leader. He excelled at many other tasks that a modern officer is asked to perform and then served capably in the civilian roles of diplomat and policy maker as well.
