Diane Hendricks didn't grow up on the inheritance of celebrities or political leaders. Instead, she spent her childhood on a dairy farm in Wisconsin — training a work ethic that eventually helped her create a business empire.

Last week, Hendricks – who has a net worth of $11.6 billion – topped Forbes' list of America's Richest Self-Made Women for the fifth year in a row. Her fortune is largely dependent on ABC Supply, a construction materials company she built with her late husband in 1982. She's currently the company's chairwoman.
