At the age of 21, Yossi Ghinsberg had romanticized dreams of adventure. Naive dreams, he now says, reflecting on the circumstances that lead him to travel to the Amazon in 1981. Ghinsberg stopped by the Speakers’ Spotlight boardroom to share news of the upcoming feature film, Jungle, based on that trip—a trip that should very well have killed him—during which bad planning, betrayal, the elements, wild animals, and luck seemed to conspire against him. Daniel Radcliffe signed up to capture the three weeks Ghinsberg spent lost and on the verge of death, but Ghinsberg himself has spent decades extracting lessons from his harrowing and devastating experience.

Some of what he’s learned actually comes off as counter-intuitive. Despite our natural urge to believe survival lessons teach us to compete for limited resources and destroy competitors, Ghinsberg says the opposite is true. He outlines that while naivety can get you in trouble, it can also lead to successes old ways of thinking cannot, and that our notions of limited resources and survival of the fittest are simply wrong.

He outlines these in inspiring, emotional stories—ones of unbelievable pain, but also perseverance—that have been perfectly aligned to offer a different way of thinking for businesses faced with future existential threats.
