Kelli Arena spent her career at CNN telling the public what powerful people would rather keep quiet. She covered the Justice Department, won an Emmy, and reported the Moussaoui trial, the only 9/11 case tried in an American civilian courtroom.

After Kelli left journalism, she went into another form of public service, serving as Chief of Communications for the National Security Agency, spending eight years helping the Agency find its voice.

Kelli has remade herself across four worlds: journalism, academia, government, and now the nonprofit sector, where she just became President and CEO of the National Cryptologic Foundation.

A few things she gets into, worth your time even if you never press play:

She took six months of maternity leave, three separate times, as an on-air correspondent. Everyone said it would end her career. It didn't. Younger women in the newsroom started thanking her, because she'd quietly given them permission.

She earned back America's trust at the NSA the boring way: Through Consistency. Relationships. A rule that every reporter got a callback within 30 minutes, even when the answer was "no comment."

And her advice for anyone starting over: "Listen more than you speak. Every single time I have listened to others before making a decision, it has been a better decision."
