Sleep has to be, by far, the most underrated aspect of good health. I think sleeping less & working more is glorified. Life is like a marathon; if you run too fast and don't pace yourself, you can burn out, and you probably won't be able to finish strong.

I believe that that is a fast-food myth to get us out there buying whatever they’re selling because I know that beans and greens are very, very affordable.

Too often women are told not to be ambitious. Girls are told not to be ambitious, to just fit in, don’t rock the boat, be happy and grateful for what you already have. And it’s like—no, the only way things change is if we start demanding what we deserve.

I think it's … the profession is starting to realise that in part it's the general climate, and the way we treat each other is not conducive for having more women in the profession. It's not just about promotion but it's about the general environment and how people talk to each other and address each other in seminars and things like that, that we need to work on a culture that is more respectful and that will be more acceptable for many women who think that they don't want to play the games of shouting at each other.

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?
