Formal learning can teach you a great deal, but many of the essential skills in life are the ones you have to develop on your own. - Lee Iacocca

There’s a world of difference between a strong ego, which is essential, and a large ego — which can be destructive. The guy with a strong ego knows his own strengths. He’s confident. He has a realistic idea of what he can accomplish, and he moves purposefully toward his goal. But the guy with a large ego is always looking for recognition. He constantly needs to be patted on the back. He thinks he’s a cut above everybody else. And he talks down to the people who work for him.

Why don’t we pass a law that says when you borrow money to buy somebody else and cannibalize him, the interest payments on those loans are not deductible? That would get the excesses out of the system pretty fast. Right now, if you want to buy up a competitor, generally you can’t. That would violate the antitrust laws. But if you want to buy a company that does something else entirely, that’s okay. Where’s the sense in that?

It's a good thing god doesn't let you look a year or two into the future, or you might be sorely tempted to shoot yourself.
