"Worldly ambition inhibits true learning." - Andrew Bacevich, "Washington Rules"

Worldly ambition inhibits true learning. Ask me. I know. A young man in a hurry is nearly uneducable: He knows what he wants and where he's headed; when it comes to looking back or entertaining heretical thoughts, he has neither the time nor the inclination. All that counts is that he is going somewhere. Only as ambition wanes does education become a possibility.
