Hugh Pickens DOT Com writes: Eric Barker writes at TheWeek that while high intelligence has its place, a large-scale study of more than three hundred creative high achievers including Leonardo da Vinci, Galileo, Beethoven, and Rembrandt has found that curiosity, passion, hard work, and persistence bordering on obsession are the hallmarks of genius. "Successful creative people tend to have two things in abundance, curiosity and drive. They are absolutely fascinated by their subject, and while others may be more brilliant, their sheer desire for accomplishment is the decisive factor," writes Tom Butler-Bowdon. It's not about formal education. "The most eminent creators were those who had received a moderate amount of education, equal to about the middle of college. Less education than that — or more — corresponded to reduced eminence for creativity," says Geoffrey Colvin. Those interested in the 10,000-hour theory of deliberate practice won't be surprised that the vast majority of them are workaholics. "Sooner or later," writes V. S. Pritchett, "the great men turn out to be all alike. They never stop working. They never lose a minute. It is very depressing." Howard Gardner, who studied geniuses like Picasso, Freud, and Stravinsky, found a similar pattern of analyzing, testing, and feedback used by all of them: "Creative individuals spend a considerable amount of time reflecting on what they are trying to accomplish, whether or not they are achieving success (and, if not, what they might do differently)." Finally genius means sacrifice. "My study reveals that, in one way or another, each of the creators became embedded in some kind of a bargain, deal, or Faustian arrangement, executed as a means of ensuring the preservation of his or her unusual gifts. In general, the creators were so caught up in the pursuit of their work mission that they sacrificed all, especially the possibility of a rounded personal existence," says Gardner. "What pervades these unusual arrangements is the conviction that unless this bargain has been compulsively adhered to, the talent may be compromised or even irretrievably lost."
