IBM's long-standing mantra is 'Think.' What has always made IBM a fascinating and compelling place for me, is the passion of the company, and its people, to apply technology and scientific thinking to major societal issues.

One of the most important things for any leader is to never let anyone else define who you are. And you define who you are. I never think of myself as being a woman CEO of this company. I think of myself as a steward of a great institution.

You have to stick up for what you believe in. And that, to me, is the biggest thing you can do about driving inclusion.

Big Data will spell the death of customer segmentation and force the marketer to understand each customer as an individual within eighteen months, or risk being left in the dust.

Clients say, 'What's your strategy,' and I say, 'Ask me what I believe first.' That's a far more enduring answer.

Your value will be not what you know; it will be what you share.

I learned to always take on things I'd never done before. Growth and comfort do not coexist.
