The book that I gift most to people, because it has had a lasting impact on my psyche, is The Warrior Within: The Philosophies of Bruce Lee. I admire Bruce Lee for his physicality, of course, but more so for his deep philosophy, known as “Jeet Kune Do” or “the way of the intercepting fist.” The key element of Jeet Kune Do is its “formless form.” Bruce Lee rejected the rigid rules and structures of Kung Fu and other traditional fighting styles. Instead, he borrowed from several styles to create his own fluid, rapidly efficient technique that was all his. In The Warrior Within, John Little explains how Bruce Lee’s philosophy helped him overcome tremendous challenges and pain to become a man whose originality, intense belief, and commitment I’ve long admired.

Over the years, I have found a few resources for developing personal productivity that I love. My top picks include Getting Things Done by David Allen, the classic The 7 Habits of Highly Effective People by Stephen R. Covey, and Learning How to Learn Barbara Oakley (I recommend the Coursera course). I'm tempted to add Tiny Habits to this list.

And this is where, a couple of years before I had become CEO, I had read this book by Carol Dweck out of Stanford [University] called “Mindset,” which was more in relation to my kids. And the simple concept in that book, which I loved a lot, was it's better to be a learn-it-all even if the know-it-all has more innate capability, because the learn-it-all ultimately will do better. And I said, well, that applies to CEOs. That applies to companies made up of people. And I said: What if we introduce that as the meme to have the cultural dialogue at Microsoft?

When I was 16 years old, I read the book from Hans Selye. Hans Selye is a Canadian scientist, but he was Hungarian so his book was translated to Hungarian. His mantra was that you have to focus on things that you can change. Many young ones are giving up because they can see that their friends or their colleagues are advancing, and it seems that they do less and somehow, they get higher salary and promoted. I told that if you notice that then you already took away your attention what you can change. Because you cannot change that.
