Ultra-endurance athlete and retired Navy SEAL David Goggins gives us a glimpse into his formative experiences and mindset shifts.

While many of us work at self-improvement, the changes we implement are often short-lived. To achieve true transformation, we must have an ironclad belief in ourselves.

After years of doubt, David Goggins found his belief, and his extraordinary accomplishments prove it.

Goggins is a former U.S. Navy SEAL, Guinness World Record-holding ultra-endurance athlete, and bestselling author.

But when he was 24, Goggins was overweight, depressed, and stuck in a dead-end job.

A follow-up to his debut memoir Can't Hurt Me, Never Finished dives deeper into the mindset that enabled the author to transform his life.

Goggins recounts his key trials before and after the success of Can't Hurt Me and explores what he learned from each experience.
