Satya Nadella

Be passionate and bold. Always keep learning. You stop doing useful things if you don't learn. So the last part to me is the key, especially if you have had some initial success. It becomes even more critical that you have the learning 'bit' always switched on.

Believe me, my journey has not been a simple journey of progress. There have been many ups and downs, and it is the choices that I made at each of those times that have helped shape what I have achieved.

What I look for when I see a piece of art for the first time is some kind of emotional, intellectual experience, that's a combination of both of those things and is informed by my knowledge and something new that I see the artist doing.

Do I sometimes hope I wake up in the morning and people are like, 'What's wrong with her? She looks emaciated.' Of course I would love that. I'm such a clothes whore, I would love the opportunity to be a hanger. But I think I'm more confident than I've ever felt in my life.

If I'm serious, yes, I'd like to have done what Shakespeare did... to act and write. You learn so much from acting. One of our great writers, Alan Bennett, does both supremely well. When I write a story, I tend to speak it aloud as I'm writing it.
