My mother was of a darker complexion than either my grandmother or grandfather.
My father was a white man. The opinion was also whispered that my master was my father; but of the correctness of this opinion, I know nothing; the means of knowing was withheld from me. My mother and I were separated when I was but an infant-before I knew her as my mother. It is a common custom, in the part of Maryland from which I ran away, to part children from their mothers at a veryearly age. Frequently, before the child has reached its twelfth month, its mother is taken from it, and hired out on some farm a considerable distance off, and the child is placed under the care of an older woman, too old for field labor. For what this separation is done, I do not know, unless it was to hinder the development of the child's affection towards its mother.
I've always been an optimist and I suppose that is rooted in my belief that the power of creativity and intelligence can make the world a better place.
For as long as I can remember, I've loved learning new things and solving problems. So when I sat down at a computer for the first time in seventh grade, I was hooked. It was a clunky old Teletype machine and it could barely do anything compared to the computers we have today. But it changed my life.
When my friend Paul Allen and I started Microsoft 30 years ago, we had a vision of "a computer on every desk and in every home," which probably sounded a little too optimistic at a time when most computers were the size of refrigerators. But we believed that personal computers would change the world. And they have. And after 30 years, I'm still as inspired by computers as I was back in seventh grade. I believe that computers are the most incredible tool we can use to feed our curiosity and inventiveness--to help us solve problems that even the smartest people couldn't solve on their own.
Like my friend Warren Buffett, I feel particularly lucky to do something every day that I love to do. He calls it "tap-dance to work." My job at Microsoft is as challenging as ever, but what makes me "tap-dance to work" is when we show people something new, like a computer that can recognize your handwriting or your speech, or one that can store a lifetime's worth of photos, and they say, "I didn't know you could do that with a PC!"
But for all the cool things that a person can do with a PC, there are lots of other ways we can put our creativity and intelligence to work to improve our world. There are still far too many people in the world whose basic needs go unmet.
I believe that my own good fortune brings with it a responsibility to give back to the world. My wife, Melinda, and I have committed to improving health and education in a way that can help as may people as possible.
As a father, I believe that the death of a child in Africa is no less poignant (辛酸的) or tragic than the death of a child anywhere else. And that it doesn't take much to make an immense difference in these children's lives.
I'm still very much an optimist, and I believe that progress on even the world's toughest problems is possible and it's happening every day. We're seeing new drugs for deadly diseases, new diagnostic tools, and new attention paid to the health problems in the developing world.
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 solve tough problems, we're going to make some amazing achievements in all these areas in my lifetime.
