Dream. Dream. Dream. Be like God, dream because God believes in you young people. Most of God’s best collaborators and partners have been young people. Joseph, David, Jeremiah, St. Francis. They are young, young, young. And in many ways Jesus was young. Many of those who have been God’s best works — fellow workers have been young. And don’t allow oldies to fill you with their cynicism and disillusionment. Dream. Dream that this world can become better as you do dream, in fact. I mean, when these young people go off and work as Peace Corps and other volunteering groups in poverty stricken places where they don’t get any better headlines for dreaming the good things. Dream. Dream. Dream. Dream that this can be a world without poverty. Dream that this can be a world without war. Dream that this is a world that will recognize that every human being matters.

One thing I state as soon as we’re out of the door: ‘Under no circumstances is anyone to say that I lost a battle with cancer. Or that I bore it bravely. I am not fighting, losing, winning or bearing.’ I will not personify the cancer cells inside me in any form. I reject all metaphors of attack or enmity in the midst, and will have nothing whatever to do with any notion of desert, punishment, fairness or unfairness, or any kind of moral causality.

History was not written by men who predicted failure, who gave up their dreams, who abandoned their principles, who allowed their laziness to put their intelligence to sleep. If certain men at times were alone in seeking victory, they always had at their side the watchful spirit of their peoples, the faith and destiny of many generations.

Being a scientist is about resilience because science is exploring the unknown, just as an immigrant is exploring the unknown. In both, you are on an uncertain journey and you have to find your own North Star.
