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

Every time you think all the technology that had been created already, all you have to do is look around and then there's someone new who's born with a new idea.

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.

It's not really about asking for the raise but knowing and having faith that the system will actually give you the right raises as you go along. And that, I think, might be one of the additional superpowers that, quite frankly, women who don't ask for raises have. Because that's good karma. It'll come back. Because somebody's going to know: 'That's the kind of person that I want to trust. That's the kind of person that I want to really give more responsibility to.'

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

The opportunity ahead for Microsoft is vast, but to seize it, we must focus clearly, move faster and continue to transform. A big part of my job is to accelerate our ability to bring innovative products to our customers more quickly.

If you are going to have a risk-taking culture, you can't really look at every failure as a failure, you've got to be able to look at the failure as a learning opportunity.
