To me, I learned along the way, you know, culture is behavior. That's all it is; culture is people's behaviors.

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.

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.

Never love something so much that you can’t let go of it.

Don't let others define you. Define yourself.
