Anyone can take these principles and apply them to their own field and be successful.

A 21 year old nearly illiterate Marine Lance Corporal with a year under his belt leading a squad overseas can outlead a whole boatload of Yalies.

Leaders are made by hard work, they are not born nor created by any school, least of all by the Ivy colleges. The most dangerous "leader" is one filled with arrogance, entitlement, and fancy ideas, ie your average Ivy League grad.
