I'm making progress if today's problems are different from yesterday's.

A peaceful world is a world in which differences are tolerated, and are not eliminated by violence.

The mark of a successful organization isn't whether or not it has problems, its whether it has the same problems it had last year.

There are plenty of problems in the world, many of them interconnected. But there is no problem which compares with this central, universal problem of saving the human race from extinction

I wouldn't attach too much importance to these student riots. I remember when I was a student at the Sorbonne in Paris, I used to go out and riot occasionally.
