“Learning is not doing; it is reflecting on doing.”

“Organizational effectiveness does not lie in that narrow minded concept called rationality. It lies in the blend of clearheaded logic and powerful intuition”

“Management is, above all, a practice where art, science, and craft meet”

“The way to learn to do things is to do things. The way to learn a trade is to work at it. Success teaches how to succeed. Begin with the determination to succeed, and the work is half done already.”

“You can't learn in school what the world is going to do next year.”

“There was clearly nothing to do but flop down on the shabby little couch and howl. So Della did it. Which instigates the moral reflection that life is made up of sobs, sniffles, and smiles, with sniffles predominating.”

“Down to the closest friend every man is a potential murderer. Often it wasn't necessary to bring out the gun or the lasso or the branding iron-- they had found subtler and more devilish ways of torturing and killing their own. For me the most excruciating agony was to have the word annihilated before it even left my mouth. I learned, by bitter experience, to hold my tongue; I learned to sit in silence, and even smile, when actually I was foaming at the mouth. I learned to shake hands and say how do you do to all this innocent-looking fiends who were only waiting for me to sit down in order to suck my blood.”
