Hard

“The author makes a compelling biological case that nature isn't a luxury - it's the environment our hardware was actually built for. In an AI-first world, where the pace of change is relentless and a different kind of grit and resilience needs to be built as a deliberate muscle, that argument feels urgent rather than optional. Going back to our roots isn't escape. It's rescue.”

Sonia Omar

GTM Director

“I work in tech. The pace doesn't let up, and I've felt my resilience threshold dropping in ways I haven't been able to name. I've also felt a stronger pull back toward nature without quite knowing why. This book gave me the language for both. It's grounded, honest, and doesn't try too hard.”

Tamara Karsten

Chief of Staff

“What struck me most is the idea that hardship, chosen deliberately, doesn't degrade the system, it upgrades it. That's such a different way to think about difficulty. It's also what separates a Quest from a Grind: hardship with a purpose and a finish line builds you, while unstructured, endless pressure just depletes you. … I've since booked my own Quest: four days at a remote hut with no electricity and no distractions, just water and time, timed for my 55th birthday next year.”

Luca Rossi

CFO

“This book made me sign up for the London Marathon, something I hadn't let myself consider in years. I have arthritis, three kids, and a job that eats every hour I have, and it would have been easy to keep finding reasons to wait. What stuck with me wasn't the running - it was the shift from someone who talks about consistency to someone who actually trains for it. I want my kids to see that.”

Laura Keith

CEO

“This book found me right as I was becoming too comfortable - cutting corners in training, at work, in life. It gave me the language for what I already sensed: that ease is not the same as progress. As a CEO, it changed how I show up: phone away in meetings, higher standards without shortcuts, real presence instead of performance. I bought copies for my entire leadership team.”

Pedram Tadayon

CEO

“This is the kind of book you finish quickly but keep thinking about long after. It's built on a mix of real experience and research, which gives it a grounded, honest quality that a lot of leadership books miss. It doesn't feel like someone handing you a framework — it feels like someone who's lived it and done the work to back it up.”

Veita Singh

Marketing Director

“I've always believed in the value of doing hard things. We all need proving grounds - experiences that test us and force us to grow. Reading Hard validated that belief - but it also refined it, changing how I think about struggle itself. Lee Arthur makes a compelling case that not all hardship is created equal. Some challenges simply leave you depleted; others fundamentally change how you see yourself and the world. Since reading the book, I've found myself looking back at some of the hardest periods of my life and thinking honestly about what was a useful struggle vs what was just really hard - and incorporating that as I think about throwing myself into new challenges and opportunities.”

Jamie Bolton

Chief Strategy Officer

“Hard is an important wake up call for executives - diminished by the ambient, chronic stress of their routine - to make steps back towards their full potential. Connecting physiological insight to relatable business & life experience, Hard can be an uncomfortable read as you recognise weak behaviours that have slipped in over time; challenging you to do better by learning lessons from traditions that have sustained human resilience for thousands of years. A valuable call to action by Lee Arthur.”

Dom Devlin

Chief Product Officer

“I read Hard as a solo founder, in the stretch where the work is real and none of it is visible yet. What it gave me was not motivation, but clarity. It was a framework that naturally fit the journey I was already on. Lee then does the part most books skip, showing how to carry what you find back into the way you lead on Monday. That is the Inner Citadel. It's not just a feeling you get on a mountain, but a structure you maintain at work and beyond.”

Tim Desoto

Founder & CEO

“As a young leader with an ever-overflowing mailbox and tendency to confuse work-related stresses with genuine emergencies, Hard immediately resonated. But beyond its resonance to a business context - Hard is deeply philosophical, exploring significant questions: how do we forge resilience? What habits shape humans who uphold an unwavering integrity, with the ability to face any challenge without crumbling? In an honest and unpatronizing way, this book delivers a practical framework for shedding away the fluff - the unnecessary murmurs of the mailbox, the unfounded anxiety, revealing the calm, focused and prepared interior beneath.”
