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.

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.
