Tim Ferriss, pictured, collects "tactics, routines, and habits" of the world's top performers.
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."
