Ginni Rometty

I've been head of strategy at IBM and together with my colleagues built our five-year plan. My priorities are going to be to continue to execute on that.

I learned to always take on things I'd never done before.

So what it means is when you don't believe in the inevitable, it means you don't expect that that's how things have to turn out. You can change them.

And so when I moved to IBM, I moved because I thought I could apply technology. I didn't actually have to do my engineer - I was an electrical engineer, but I could apply it. And that was when I changed. And when I got there, though, I have to say, at the time, I really never felt there was a constraint about being a woman. I really did not.

And the reason I came to IBM was I think - I always say at a really early age, I learned you've got to be passionate about what you do. No matter what it is, you put too much, your heart and soul in it, you have to be passionate about it. You make too many sacrifices.

If you're clear on what you believe, you have a great foundation to go make a market.
