Maggie Wilderotter and Denise Morrison are the much-discussed sister act of the corporate world. As the CEOs of Frontier Communications and Campbell Soup, respectively, the duo claims their parents are the source of their confidence and business savvy. Onstage at the 2011 Fortune Most Powerful Women Summit with her big sister, Wilderotter reminisced, "Every Saturday morning, we had jobs in jars and we were responsible to do those to get our allowance."

"And we could barter," Morrison interrupted. "We did business plans on anything we wanted," Wilderotter continued. "Like getting our ears pierced... We had to wear screw back earrings to prove to our dad that it wasn't a fad - for a year!" Morrison added. The attention to detail, being thorough, and being innovative at a young age, the sisters say, helped them with future business plans.

Fun fact: Bruce Springsteen's dad pierced their ears in New Jersey.
