Everything I am going to say to you is the child of a conversation. [...] That is the aspect of conversation that particularly excites me: how conversation changes the way you see the world, and even changes the world.

Each person is an enigma. You're a puzzle not only to yourself but also to everyone else, and the great mystery of our time is how we penetrate this puzzle.

Change the way you think, and you are halfway to changing the world.

What we make of people, and what we see in the mirror when we look at ourselves, depends on what we know of the world, what we believe to be possible, what memories we have, and whether our loyalties are to the past, the present or the future.

Nothing influences our ability to cope with the difficulties of our existence so much as the context in which we view them; the more contexts we can choose between, the less do the difficulties appear to be inevitable and insurmountable.

Never before have humans been so ambitious, have they thought that they could be much more than their parents were.

I think the hero in our generation is not the individual but the pair, two people who together add up to more than they are apart.
