This episode is one that's close to the heart.

Luke Russard is a best-selling author and the award-winning news correspondent and son of the late great journalist Tim Russert.

Back in 2008, shortly after his father's death,

Russert joined NBC News just out of college. Countering the skeptics, he worked hard and became an important piece of political news coverage, like his dad. He spent eight years

covering midterm and presidential elections, reporting on some of the biggest political

issues of our time. His work earned him Emmy nominations for best reporting and outstanding live coverage

before he made the surprising decision to resign in 2016.

Ressert then embarked on a journey of self-discovery,

traveling to more than 60 countries to discover his true purpose.

Earlier this year, he released his memoir,

relationship with his dad and reflects on his life and why he needed to leave everything to discover

its meaning. Russert's memoir is now a New York Times bestseller.

been on a journey. What has it been like to go through these years and be writing a book?

I didn't necessarily know what my purpose was. I didn't feel fulfilled. I liked the work,

but some days it left me empty.

So I wanted to sort of figure that out and answer that question. And it turned into what was

supposed to be about six months of travel into a three-year odyssey around six continents and

over 65 countries and trying to figure out, okay, who are you independent of your parents? Who

are you independent of your profession, your hometown, and what are you really about?
