Since writing his 2007 book “The 4-Hour Workweek,” Tim Ferriss has built a career around collecting the, as he puts it, “tactics, routines, and habits,” of the world’s top performers, from Navy SEALs to entrepreneurs.

His new book “Tools of Titans” is a collection of those lessons, drawn from more than 100 interviews he conducted for the book and his hit podcast, “The Tim Ferriss Show.”

Ferriss recently stopped by Business Insider’s New York office to talk about “Tools of Titans” for a Facebook Live Q&A. Since he always asks his guests about their favorite books, we decided to do the same.

He shared with us the five books he considers to have had the biggest influence on his life, saying that he keeps them face-out on the book shelf in his living room, “so that I see them regularly, to remind me of the lessons I took from them.”


'Moral Letters to Lucilius' by Seneca the Younger

Ferriss has long had an obsession with Stoicism, the school of ancient Greek philosophy that was also adopted by Roman thinkers.

The most famous work of Stoicism may be the philosopher king Marcus Aurelius' "Meditations," of which Ferriss is a fan, but he's especially taken with Seneca's letters to his student Lucilious. The collection is, as Ferriss said, "about everything imaginable, and it's as applicable today as it was 2,000 years ago."

"Stoicism as a whole I think is the optimal operating system for thriving in high stress environments," he said.

'Surely You're Joking, Mr. Feynman!' by Richard Feynman

Richard Feynman was a Nobel-prize winning physicist who was a bit of a Renaissance man. His book "Surely You're Joking, Mr. Feynman!", first published in 1985, is a collection of his autobiographical writings.

Ferriss has adopted Feynman's approach to life. He said the book "paints a picture of a very brilliant problem solver and merry prankster who was a polymath, taught himself how to play the bongos, used to paint in strip clubs. You've got to love this guy! And it's a hilarious book but it also shows you how good he was at testing assumptions and questioning dogma. Even in the face of embarrassment or criticism."

'Zorba the Greek' by Nikos Kazantzakis

Ferriss said that after interviewing more than 100 high performers, he saw that true success should be defined as continuing to achieve while appreciating what one already has.

He explained that the 1946 novel "Zorba the Greek" by Nikos Kazantzakis captures this insight. It tells the story of an academic who sets aside his books to immerse himself in the world.

"'Zorba the Greek' is a really good read for trying to chill out that Type A drive ... piece of yourself, so that you can actually enjoy the ride," Ferriss said.

'Dune' by Frank Herbert

It may be a little off-putting to hear Ferriss say "all you need to know about leadership" is contained in "Dune," the 1965 sci-fi epic by Frank Herbert that tells the story of a sadistic intergalactic despot and his superhuman son who fuses his mind with a giant sand worm.

But two quotes by the late author lend insight. In a 1979 interview Herbert said, "The bottom line of the 'Dune' trilogy is: Beware of heroes. Much better [to] rely on your own judgment, and your own mistakes."

And in 1985 Herbert wrote, "'Dune' was aimed at this whole idea of the infallible leader because my view of history says that mistakes made by a leader - or made in a leader's name - are amplified by the numbers who follow without question."

'The Effective Executive,' by Peter F. Drucker

"The Effective Executive" is a classic management book by Peter Drucker that was first published in 1967. It's about the way being effective (choosing the right things to attack) should be prioritized over being efficient (doing things quickly).

"I think it's much more valuable than 99% of the so-called time management books out there," Ferriss said.
