    For years, I have advocated the importance of hard work, determination, persistence, and practice as key ingredients of success. Malcolm Gladwell, who has written The Story of Success, seems to support my theory. He says it takes about 10,000 hours of practice to attain true expertise.

“The people at the very top don’t just work harder than everyone else,” Gladwell writes. “They work much, much harder.” Achievement, he says, is talent plus preparation. Preparation seems to play a bigger role.

For example, he describes the Beatles: They had been together seven years before their famous arrival in America. They spent a lot of time playing in clubs, sometimes for as long as eight hours a night. Overnight success? Not exactly. Estimates are that the band performed 1,200 times before their big success in 1964. By comparison, most bands don’t perform 1,200 times in their careers.

Neurologist Daniel Levitin has studied the formula for success extensively and shares this finding: “The emerging picture from such studies is that 10,000 hours of practice is required to achieve the level of mastery associated with being a world-class expert in anything. In study after study of composers, basketball players, fiction writers, ice skaters, concert pianists, chess players, the number comes up again and again. Of course, this doesn’t address why some people get more out of their practice sessions than others do. But no one has yet found a case in which true world-class expertise was accomplished in less time. It seems it takes the brain a long time to digest all that it needs to know to achieve true mastery.”

Two computer giants, Bill Joy, who co-founded Sun Microsystems, and Bill Gates, co-founder of Microsoft, also were proof of the 10,000-hour theory.

The abilities these people possessed were far-ranging, yet the formula for success was the same: hard work and lots of it. Some people just make it look easy. Of course, you probably didn’t see the first 9,999 hours of hard work.
