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

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.

Many companies aspire to change the world. But very few have all the elements required: talent, resources and perseverance. Microsoft has proven that it has all three in abundance.

A lot of people are joking about the Windows 10 error message that says 'Something Happened'. Well, that's not on me. My original idea was to not have any errors at all, and for the operating system to be called Windows RT ME One.

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.

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

The way I measure my life is 'Am I better than I was last year?'
