The idea that excellence at performing a complex task requires a critical minimum level of practice surfaces again and again in studies of expertise.… - Malcolm Gladwell

When people are overwhelmed with information and develop immunity to traditional forms of communication, they turn instead for advice and information to the people in their lives whom they respect, admire, and trust. The cure for immunity is finding Mavens, Connectors, and Salesmen.

"Preschoolers make a number of assumptions about words and their meaning as they acquire language, one of the most important of which is what the psychologist Ellen Markman calls the principle of mutual exclusivity. Simply put, this means that small children have difficulty believing that any one object can have two different names. The natural assumption of children, Markman argues, is that if an object or person is given a second label, then that label must refer to some secondary property or attribute of that object. You can see how useful this assumption is to a child faced with the extraordinary task of assigning a word to everything in the world. A child who learns the word elephant knows, with absolute certainty, that it is something different from a dog. Each new word makes the child's knowledge of the world more precise. Without mutual exclusivity, by contrast, if a child thought that elephant could simply be another label for dog, then each new word would make the world seem more complicated. Mutual exclusivity also helps the child think clearly. "Suppose," Markman writes, "a child who already knows 'apple' and 'red' hears someone refer to an apple as 'round.' By mutual exclusivity, the child can eliminate the object (apple) and its color (red) as the meaning of 'round' and can try to analyze the object for some other property to label.

"Grazer and Cohn - two outsiders with learning disabilities-played a trick. They bluffed their way into professions that would have been closed to them. The man in the cab assumed that no one would be so audacious as to say he knew how to trade options if he didn't. And it never occurred to the people Brian Grazer called that when he said he was Brian Grazer from Warner Brothers, what he meant was that he was Brian Grazer who pushed the mail cart around at Warner Brothers. What they did is not "right," just as it is not "right" to send children against police dogs. But we need to remember that our definition of what right is, often as not, simply the way that people in positions of privilege close the door on those on the outside. David has nothing to lose, and because he has nothing to lose, he has the freedom to thumb his nose at the rules set by others. That's how people with brains a little bit different from the rest of ours get jobs as options traders and Hollywood producers-and a small band of protesters armed with nothing but their wits have a chance against the likes of Bull Connor"
