Ryan Holiday: "Peter [Thiel] would, at one point, pass me a copy of 'The Fifteen Decisive Battles of the World', the book he had read as he’d mulled his options over."

Brian Armstrong: "Celebrate the creators in the world (even when they struggle). They may be more valuable than we think."

Blake Scholl: "Far and away my favorite book is Atlas Shrugged"

Elon Musk: "Very appealing if you're a sophomore in college. A counterpoint to communism and useful as such, but should be tempered with kindness."

Peter Thiel: "When I first read [Atlas Shrugged] in the 80s, it felt pretty crazy, and in the last decade, in many ways it's felt much more correct"

Travis Kalanick mentioned 'Atlas Shrugged' in a Washington Post interview.

Fred Wilson recommends 'Atlas Shrugged' for entrepreneurs.

Peter Thiel: “It can sometimes seem as if one must learn everything old before one can try anything new.

Adam Grant does a masterful job showing that is not the case; we are lucky to have him as a guide.”

Sheryl Sandberg: “Originals is one of the most important and captivating books I have ever read, full of surprising and powerful ideas.

It will not only change the way you see the world; it might just change the way you live your life. And it could very well inspire you to change your world.”

Arianna Huffington: “Originals is a fascinating, eye-opening read that will help you not just recognize your own unique gifts, but find the strength to challenge conventional wisdom to bring them to life.

Using surprising studies and riveting stories, Adam Grant brilliantly shows us how to champion new ideas, bust persistent myths that hold us back and change not only our lives, but our world.”

Seth Godin: “An urgent must read, a seminal work that will surprise you on every single page.

Adam Grant has reset our expectations for what it means to be creative and what's required to make a difference. Share it with someone you care about.”

One of Richard Branson's top books to read in a lifetime.

Anthony Pompliano: "One of the best books I read in 2017"

Peter Thiel: "There is no better way to think about human irrationality than to read Dostoevsky, and there is no better reader of Dostoevsky than Mr. Girard."

Peter Thiel: "We [followers of Girard], had sort of a sense that we had figured out the truth about the world in a way that nobody else did."

Kanye West: "I’ll be working on home designs and looking at references from 3,000 years ago and reading the Old Testament at the same time.

It’s like a soundtrack to the visuals and shapes…of what we’re creating”

Peter Thiel says The New Testament has influenced him more than The Old Testament.

Donald Trump: "The bible means a lot to me"

Reed Hastings: "The forces of competition are just incredibly strong. Everyone is trying to eat your lunch, and if you don’t read 7 Powers you’re going to die a lot sooner."

Peter Thiel: "Hamilton Helmer understands that strategy starts with invention. He can't tell you what to invent, but he can and does show what it takes for a new invention to become a valuable business"

Patrick Collison: "Correctly places enormous value on execution and on culture. However, I think this sometimes leads to insufficient importance being placed on strategy.

Hamilton Helmer's deeply incisive work will hopefully help correct that"

Daniel Ek: "Hamilton Helmer is the best kind of big thinker – he offers great insights that you can turn into real world action.

At Spotify the 7 Powers are widely used as we discuss new initiatives.

His distillation of the key types of strategic power, how to find them, how to leverage them, and how to maintain them is a fantastic toolset for companies at every stage.”

One of the books Keith Rabois recommends for entrepreneurs.

One of Peter Thiel's favorite books.

Fred Wilson: "Chapter five in 'The Hard Thing About Hard Things' is possibly the best thing I’ve read about leading a tech company"

Peter Thiel: “Every management guide presumes that all great companies follow a formula. But successful startups don’t imitate; they build innovations that can’t be copied.

Ben Horowitz knows no recipe guarantees success. He has written the first true guide for protecting a startup from self-sabotage.”

Raoul Pal: "Without question, to me, The Hard Thing About Hard Things by Ben Horowitz is, by far, the best, most brutally honest and incredibly useful book about the realities of starting and running a company, ever written."

Tim Ferriss: "A great book"

Larry Page: "Ben's book is a great read - with uncomfortable truths about entrepreneurship and how to lead to a company.

It's also an inspiring story of a business rebirth through sheer willpower."

Marc Andreessen mentioned 'The Hard Thing about Hard Things' on 'The Tim Ferriss Show' podcast.

Blake Scholl: "'The Hard Thing about Hard Things' is good."

One of five business books Chris Dixon recommended on Twitter.

One of Peter Thiel's favorite books.

Naval Ravikant: "Great book."

Seth Godin: "If you read Diamond Age before you’ve thought about molecular anything or 3D printing, then it changes your mind."

Peter Thiel: "He tells how the Nazis and the Soviets drove each other to ever more murderous atrocities as they fought to dominate Eastern Europe in the 1930s and ’40s.

Even as he calculates the death toll painstakingly, Mr. Snyder reminds us that the most important number is one: Each victim was an individual whose life cannot be reduced to the violence that cut it short."

Ryan Holiday: "Something in these pages planted itself deep into [Peter Thiel]’s mind when he first read it long ago."

Peter Thiel: "Sets the stakes for the most urgent public debate of the 2020s: How do we get back to the future?"

Naval Ravikant: "Best book I've read since Sapiens (far less mainstream, though)."

Brian Armstrong: "Was really ahead of it's time, a lot of original thinking (some really out there stuff too)."

Peter Thiel: "This book breaks the taboo on prophecy: We're not supposed to talk about a future that doesn't include the powerful states that rule over us today.

Rees-Mogg and Davidson argue that national governments could soon become as antiquated as 19th-century empires."

Elon Musk: "I know it's cliche, but Lord of the Rings is my favorite book ever."

Paul Graham's answer to "Any book recommendations for young adults?"

Reid Hoffman: "The book that I’ve most often read is Tolkien’s The Lord of the Rings.

Because it’s so important to show this journey of these hobbits, these little people in a hero’s journey about how you can change the world within a context where Tolkien is fairly sophisticated around the questions of the corruption of power, the intersection of races, and the needs for us all to work together."

One of Peter Thiel's favorite books.

Peter Thiel: "For a fresh application of Mr. Girard’s insights into power politics, that great international theater of irrationality."

One of Peter Thiel's favorite books.

Peter Thiel: "First published in 2011, but its message is evergreen: how scientists are directly attacking the problem of aging and death and why we should fight for life instead of accepting decay as inevitable.

The goal of longer life doesn’t just mean more years at the margin; it means a healthier old age."

Peter Thiel: "It was John Locke, in The Reasonableness of Christianity, said that Christ obviously had to mislead people, since if he had not done so, the authorities might have tried to kill him."
