Jenny Ming launched and ran the all-American brand Old Navy and now leads Charlotte Russe. She has been named one of the most powerful women in American business by Fortune and one of the nation's top managers by Businessweek.
But she didn't start out as the prototypical CEO. She grew up as the shy Chinese girl in San Francisco's Chinatown, named "Most Bashful" in high school. Once a manager told her she would "never make it in this business because you are such a pushover."
How did she make the leap from overlooked to high-powered retail executive? Ming tells CNBC Make It that the key to her success, and other women's, comes down to a fundamental rule: "Never underestimate yourself."
