He calls it "tap-dancing to work."
My job at Microsoft is as challenging as ever,
but what makes me "tap-dance to work" is when weshow people something new,

My wife, Melinda, and I have committed to improving health and education in a way that canhelp as many people as possible.
As a father, I believe that the death of a child in Africa is no less poignant or tragic than thedeath of a child anywhere else.

I'm excited by the possibilities I see for medicine, for education and, of course, for technology.
And I believe that through our natural inventiveness, creativity and willingness to solvetough problems,
we're going to make some amazing achievements in all these areas in my lifetime
