If you could have a gigantic billboard anywhere, what would it say and why?

If silence seems to give approval, then remaining silent is cowardly.

Yes, if you want to say that I was a drum major, say that I was a drum major for justice. Say that I was a drum major for peace. I was a drum major for righteousness. And all of the other shallow things will not matter.

The first principle is that you must not fool yourself—and you are the easiest person to fool. So you have to be very careful about that. After you've not fooled yourself, it's easy not to fool other scientists. You just have to be honest in a conventional way after that.

And let me offer lesson number one about America: All great change in America begins at the dinner table. So, tomorrow night in the kitchen I hope the talking begins. And children, if your parents haven't been teaching you what it means to be an American, let 'em know and nail 'em on it. That would be a very American thing to do.

Peace is not unity in similarity but unity in diversity, in the comparison and conciliation of differences.

I share Alfred Nobel's conviction that war is the greatest of all human disasters. Infectious disease runs a good second.

At the age of 21, as a Moeid, I believed that behind every universal phenomenon there must be beauty and simplicity in its description. This belief remains true today.

In this new century, we must start from the understanding that peace belongs not only to states or peoples, but to each and every member of those communities. The sovereignty of States must no longer be used as a shield for gross violations of human rights. Peace must be made real and tangible in the daily existence of every individual in need. Peace must be sought, above all, because it is the condition for every member of the human family to live a life of dignity and security.

War may sometimes be a necessary evil. But no matter how necessary, it is always an evil, never a good. We will not learn how to live together in peace by killing each other's children.

In the course of history, there comes a time when humanity is called to shift to a new level of consciousness, to reach a higher moral ground. A time when we have to shed our fear and give hope to each other. That time is now.

In a poverty-free world, the only place you would be able to see poverty is in the poverty museums. When school children take a tour of the poverty museums, they would be horrified to see the misery and indignity that some human beings had to go through. They would blame their forefathers for tolerating this inhuman condition, which existed for so long, for so many people.

There's the world's work to be done, and there are never enough citizens with determined hearts, courageous character, intelligent minds, and idealistic souls to do it. Yes, our world already has quite enough guns, political platitudes, arrogance, disingenuousness, self-interest, snobbishness, superficiality, war, and the certainty that God is on one side or the other. But it never has enough conscience, nor enough tolerance, idealism, justice, compassion, wisdom, humility, self-sacrifice for the greater good, integrity, courtesy, poetry, laughter, and generosity of substance and spirit. It is these elements that I urge you to carry into your careers, and remember that the great game of life is not about money; it is about doing your best to build the world anew.

One of the things, Bradman said has stayed in my mind. That the finest of athletes had, along with skill, a few more essential qualities: to conduct their life with dignity, with integrity, with courage and modesty. All this he believed, were totally compatible with pride, ambition, determination and competitiveness. Maybe those words should be put up in cricket dressing rooms all over the world.

We cannot afford to be color blind. We have to be color brave. We have to be willing, as teachers and parents and entrepreneurs and scientists, we have to be willing to have proactive conversations about race with honesty and understanding and courage, not because it's the right thing to do, but because it's the smart thing to do, because our businesses and our products and our science, our research, all of that will be better with greater diversity.

Why is it that countries which we call strong are so powerful in creating wars but are so weak in bringing peace? Why is it that giving guns is so easy but giving books is so hard? Why is it, why is it that making tanks is so easy, but building schools is so hard?

GIVE ME THE RESPECT I'VE EARNED AND GIVE IT TO MY WOLF PACK TOO.

Do not despair of our present difficulties but believe always in the promise and greatness of America, because nothing is inevitable here. Americans never quit. We never surrender. We never hide from history. We make history.

Taking action means saying 'no' to indifference. If there is a war to be waged, it is the war against the indifference which is eating away at our societies.

Tear down walls of ignorance and narrow-mindedness, for nothing has to stay as it is.

To be remembered for all the things that you do and as someone who makes people smile, touches people's lives – that is what should wake you up every single morning.
