Change is the law of life. And those who look only...

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.

The great secret that all old people share is that you really haven't changed in seventy or eighty years. Your body changes, but you don't change at all. And that, of course, causes great confusion.

One of the many things nobody ever tells you about middle age is that it's such a nice change from being young.

My notion of a wife at 40 is that a man should be able to change her, like a bank note, for two 20s.

If you're old, don't try to change yourself, change your environment.

We live in an age when to be young and to be indifferent can be no longer synonymous. We must prepare for the coming hour. The claims of the Future are represented by suffering millions and the Youth of a Nation are the trustees of Posterity.

This is the first age that's ever paid much attention to the future, which is a little ironic since we may not have one.

High expectations weren't nurtured in my neck of nowhere back then - children weren't fawned over from an early age as 'gifted' and groomed for a prizewinning future self-esteem was considered something you had to pick from the garden yourself.

A great source of calamity lies in regret and anticipation therefore a person is wise who thinks of the present alone, regardless of the past or future.

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.

There is a fountain of youth: it is your mind, your talents, the creativity you bring to your life and the lives of people you love. When you learn to tap this source, you will truly have defeated age.

Life would be infinitely happier if we could only be born at the age of eighty and gradually approach eighteen.

Probably the happiest period in life most frequently is in middle age, when the eager passions of youth are cooled, and the infirmities of age not yet begun as we see that the shadows, which are at morning and evening so large, almost entirely disappear at midday.
