Leadership and learning are indispensable to each ...

We prefer world law in the age of self-determination to world war in the age of mass extermination.

I think this is the most extraordinary collection of talent, of human knowledge, that has ever been gathered at the White House - with the possible exception of when Thomas Jefferson dined alone.

Unconditional war can no longer lead to unconditional victory. It can no longer serve to settle disputes... can no longer be of concern to great powers alone.

Leadership is the other side of the coin of loneliness, and he who is a leader must always act alone. And acting alone, accept everything alone.

A leader does not deserve the name unless he is willing occasionally to stand alone.

But no nation can base its survival and development on luck and prayers alone while its leadership fritters away every available opportunity for success and concrete achievement.

Outstanding leaders go out of their way to boost the self-esteem of their personnel. If people believe in themselves, it's amazing what they can accomplish.

Anyone who stops learning is old, whether at twenty or eighty. Anyone who keeps learning stays young. The greatest thing in life is to keep your mind young.

It is utterly false and cruelly arbitrary to put all the play and learning into childhood, all the work into middle age, and all the regrets into old age.

In youth we learn in age we understand.

A major advantage of age is learning to accept people without passing judgment.
