The top-performing salespeople in a study at a software company were the "ambiverts," those who were neither very extroverted nor extremely introverted, writes Daniel H. Pink. These people earned average hourly revenues of $155, beating extroverts by 24%. The salespeople who did the best of all, earning an average of $208 per hour, had scores squarely in the middle of a psychological scale that measures introversion and extroversion. The vast majority of people are ambiverts, which means the vast majority of people can learn to sell, Pink says.
