Warren Buffett's Wisdom on How to Succeed in Business
"What if you could buy 10% of one of your classmates and their future earnings? You wouldn't buy the ones with the highest IQ, the best grades, etc, but the most effective. You like people who are generous, go out of their way, straight shooters. Now imagine that you could short 10% of one of your classmates. This part is usually more fun as you start looking around the room. You wouldn't choose the ones with the poorest grades. Look for people nobody wants to be around, that are obnoxious or like to take all the credit. If you have a 500 HP engine and only get 50 HP out of it, you'll be beat by someone else that has a 300 HP engine but gets 250 HP output. The difference between potential and output comes from human qualities. You can make a list of the qualities you admire and those you despise. To turn the tables, think if this is the way I react to the qualities on the list, which is the way the world will react to me. You can learn to turn on those qualities you want and turn off those qualities you wish to avoid. The chains of habit are too light to be felt until they are too heavy to be broken. You can't change at 60; the time to look at that list is now."
