"The thing I'm most focused on today is, how am I maximizing the effectiveness of the leadership team..." — Satya Nadella

When I think about my career, my successes are built on learning from failures.

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.

One thing we've talked a lot about, even in the first leadership meeting, was, what's the purpose of our leadership team? The framework we came up with is the notion that our purpose is to bring clarity, alignment and intensity.

To me, Microsoft is about empowerment... we are the original democratizing force, putting a PC in every home and every desk.
