This edition of Hewitt One-to-One features an interview with Geoffrey Colvin, senior editor at FORTUNE magazine. He shares insight from his recent book entitled Talent is Overrated: What Really Separates World-Class Performers from Everybody Else.

Hewitt's Bob Gandossy and Colvin discuss what enables top performers to achieve greatness. Colvin's premise is that top performers in any field — from Tiger Woods and Winston Churchill to Warren Buffett and Jack Welch — are not determined by their inborn talents. Greatness doesn't come from DNA but from practice and perseverance honed over decades.

And not just plain old hard work, like your grandmother might have advocated, but a very specific kind of work. The key is how you practice, how you analyze the results of your progress and learn from your mistakes, that enables you to achieve greatness.
