The theme this week is "underdogs." John Chen has history in this department: His parents escaped communist China to Hong Kong, and his father had to work jobs beneath his education level so Chen could have a shot at a better life. At age 17 he came to the United States to finish high school. After he entered the workforce, Chen hit a roadblock. It wasn't common at the time for engineers to get promoted into broader management positions, and he was still growing in his comfort with communicating as a leader in English, his second language.

Fast-forward to today, and Chen has been CEO of BlackBerry for five years. He has taken the company from a dying smartphone maker to a stable provider of security and automotive software. And it's not Chen's first turnaround; after becoming CEO of Sybase in 1998, he led a reinvention that saved the company.

In all of my years covering Chen, I'd never heard his personal story. For the Fortt Knox 1-on-1 this week, I finally get to the root of why Chen is so comfortable playing the long game when it comes to leadership ... and how it ties back into the sacrifices he saw as an immigrant and the son of refugees.
