-- Bill Gates, Harvard Commencement address 6.07.07.

"Be activists. Take on the big inequities. It will be one of the great experiences of your lives....You graduates are coming of age in an amazing time. As you leave Harvard, you have technology that members of my class never had. You have awareness of global inequity, which we did not have. And with that awareness, you likely also have an informed conscience that will torment you if you abandon these people whose lives you could change with very little effort. You have more than we had; you must start sooner, and carry on longer."
