Our mission of empowering every person and every organization on the planet to achieve more is really a look back to the very creation of Microsoft.

This is a software-powered world.

Like anyone else, a lot of what I do and how I think has been shaped by my family and my overall life experience. Many who know me say I am also defined by my curiosity and thirst for learning. I buy more books than I can finish. I sign up for more online courses than I can complete. I fundamentally believe that if you are not learning new things, you stop doing great and useful things. So family, curiosity and hunger for knowledge all define me.

Our first-party devices will light up digital work and life. Surface Pro 3 is a great example -- it is the world's best productivity tablet. In addition, we will build first-party hardware to stimulate more demand for the entire Windows ecosystem. That means at times we'll develop new categories like we did with Surface. It also means we will responsibly make the market for Windows Phone, which is our goal with the Nokia devices and services acquisition.

Our ambitions are bold and so must be our desire to change and evolve our culture.

You renew yourself every day. Sometimes you're successful, sometimes your not, but it's the average that counts.

One of the key things in the tech business in particular is that you need to be able to push boundaries.
