Mental toughness is often misunderstood as being fearless, unemotional, or endlessly motivated.
But according to David Goggins, true mental toughness has little to do with feeling strong all the time.

Goggins' life story is one of transformation.
Before becoming a Navy SEAL, ultramarathon runner, and bestselling author, he struggled with obesity, self-doubt, and a difficult childhood.
