I recommend Joe Rogan Experience #1080 - David Goggins.

In this episode, Joe Rogan interviews David Goggins, a retired Navy SEAL and current world-leading endurance athlete who has run many of the hardest races in the world many times and once held the Guinness World Record for pull-ups in a day by completing 4,030 in 17 hours.

Goggins is one of the toughest individuals alive, both physically and mentally. When I first heard him speak two years ago, he made me realize how relatively weak I was, both physically and mentally.

This interview in which he tells his story provides a solid introduction to the man who continues to inspire me to push harder and go further.
