Scientists are people who are curious and want to pursue knowledge and pursue truth, and this still remains the most timeless and priceless value of a scientific career. My advice to an early-career scientist is to remain true to your passion and curiosity and that sense of mission to discover knowledge and uncover innovation. It's also very important to be using the tools of the moment, of the century. There are a lot of new tools to uplevel our own scientific research and scientific quest.

I go back to this idea that I only discovered when I was older. I wish I had known it when I was younger, because I think I missed a lot of observations in life. That is to develop your own philosophy. I always thought philosophy was one of the most useless subjects in the world.

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.

I know it is utterly fanciful to expect professional cricketers to play the game like amateurs; but the trick, I believe, is taking the spirit of the amateur - of discovery, of learning, of pure joy, of playing by the rules - into our profession. Taking it to practice or play, even when there's an epidemic of white-line fever breaking out all over the field.

It went from publisher to publisher to publisher. All of them refused it. They gave the same reasons, until a small publisher picked it up. From 1960 to 1963, three years, it didn’t sell 1500 copies. Nobody wanted to read it. It doesn’t matter. I am not here to sell, I’m here to write.

After the war — I was 15 when I entered the camp, I was 16 when I left it, and all of a sudden you become an orphan and you have no one. I had a little sister and I knew, with my mother the first night, that they were swept away by fire. My older sisters I discovered by accident after the war in Paris, where I was in an orphanage. But to be an orphan — you can become an orphan at 50, you are still an orphan. Very often I think of my father and my mother. At any important moment in my life, they are there, thinking, “What an injustice.”

I remember the awakening that occurred in me when I read, for the first time, Franz Kafka. ... That morning I was happy. I wanted to run out and embrace them, all these garbage collectors, because they taught me that there was another world than the world of Kafka, which is absurd and desperate, and despairing.

Well, naturally, my grandfather. He was a Hasid, meaning a member of the Hasidic community, and I loved him, I adored him. So thanks to him, I became a Hasid too. And my mother — who actually continued his tradition — she’s the one who brought me to Hasidic Masters. And all the stories I tell now — I’ve written so many books with Hasidic tales — these are not mine, these are theirs, my mother’s and my grandfather’s. My father taught me how to reason, how to reach my mind. My soul belonged to my grandfather and my mother. They enriched me, of course. They influenced me profoundly, to this day. When I write, I have the feeling, literally, physically, that one of them is behind my back, looking over my shoulder and reading what I’m writing. I’m terribly afraid of their judgment.
