Bear Grylls sat down with Steven Bartlett for one of The Diary of a CEO's most inspiring episodes — covering his broken back, SAS selection, the moments he almost died, and why real strength has nothing to do with muscles.
Most people know Bear Grylls as the guy who drinks his own urine on TV and eats insects in the jungle. But his conversation on The Diary of a CEO revealed a completely different side — one of deep vulnerability, genuine fear, and a faith that carried him through moments most humans will never experience.
This wasn't a survival tips episode. It was a masterclass in resilience, and the lessons apply whether you're climbing Everest or trying to get through a difficult Monday.
At 21, Bear Grylls was a member of the British Special Air Service (SAS) — one of the world's most elite military units. During a freefall parachuting exercise in Southern Africa, his parachute ripped at 16,000 feet. He hit the ground and shattered three vertebrae.
Doctors told him he might never walk again. He spent months in military rehabilitation, strapped to a bed, staring at the ceiling. It was in those months that the foundations of his entire philosophy were built.
"The mountain doesn't care about your CV. It doesn't care about your Instagram followers. It only cares about who you really are when everything is stripped away."
He told Steven Bartlett that breaking his back was the most important thing that ever happened to him — not despite the pain, but because of it. It taught him that his identity wasn't tied to his physical abilities. It forced him to rebuild from zero and discover what actually drives him.
Bear was refreshingly honest about fear. He admitted to being terrified regularly — of heights, of dangerous situations, of failing publicly. The difference isn't that he doesn't feel fear. It's that he's trained himself to act anyway.
He shared a technique he learned in the SAS: when fear hits, you have about three seconds before your rational brain shuts down and your survival instincts take over. In those three seconds, you have to make a decision and move. Hesitation is what kills people — in the mountains and in life.
This applies directly to everyday situations. Afraid to have a difficult conversation? Afraid to start a business? Afraid to leave a relationship? The fear won't disappear. But you can train yourself to act within that three-second window.
One of the most practical frameworks Bear shared was what he calls the "10% principle." When you're facing something overwhelming — whether it's climbing a mountain or building a company — you don't need to solve the whole problem. You just need to focus on the next 10%.
On Everest, he never thought about the summit. He thought about the next camp. The next hundred metres. The next step. Breaking enormous challenges into tiny, manageable chunks is how humans achieve things that seem impossible from the bottom.
Bear spoke extensively about the importance of who you surround yourself with. In survival situations, your team is everything. One weak link, one person who panics, one person who gives up — and everyone dies.
He applies this same principle to his business and personal life. He actively curates his inner circle, not based on talent or status, but on character. The three qualities he looks for: kindness, humility, and tenacity. Everything else can be taught.
"In the wild, I've learned that the strongest people aren't the ones with the biggest muscles. They're the ones with the biggest hearts. The ones who look after others when they're exhausted themselves."
Unlike many podcast guests who avoid the topic, Bear Grylls was open about his Christian faith and the role it plays in his life. He described it not as a crutch but as an anchor — something that gives him peace in situations where logic and planning run out.
Whether or not you share his faith, his point was universal: everyone needs something bigger than themselves to hold onto. For some it's faith, for others it's family, purpose, or service. The people who break in extreme situations are almost always the ones who have nothing beyond themselves to draw strength from.
Bear's most counterintuitive lesson was about comfort. He argued that the modern obsession with convenience and comfort is making us weaker — physically, mentally, and emotionally. Every system in your body, from your muscles to your immune system to your psychological resilience, grows stronger through stress and challenge, not through ease.
He doesn't advocate for unnecessary suffering. But he believes that voluntarily choosing discomfort — cold showers, physical challenges, difficult conversations, taking risks — is essential for maintaining your capacity to handle the involuntary discomfort that life inevitably delivers.

At the end of the episode, Steven Bartlett asked Bear for one piece of advice he'd give to his younger self. Bear's answer was simple:
"Be kind, be brave, and never give up. Everything else will sort itself out."
It's deceptively simple. But from a man who has climbed Everest, crossed the North Atlantic in an inflatable boat, and survived a broken back — simplicity earned through experience carries more weight than complexity born from theory.
