The compensation of a very early success is a conviction that life is a romantic matter. In the best sense one stays young.

Age is not better, hardly so well, qualified for an instructor as youth, for it has not profited so much as it has lost.

Cast me not off in the time of old age; forsake me not when my strength faileth.

I remember my youth and the feeling that I could last forever, outlast the sea, the earth and all men.

Age in a virtuous person, of either sex, carries in it an authority which makes it preferable to all the pleasures of youth.

The wiser mind mourns less for what age takes away than what it leaves behind.

We do not quit playing because we grow old, we grow old because we quit playing.

Towering in the confidence of twenty-one.

These are the arks, the trophies, I erect, That fortify thy name against old age.

The deepest thing in any one is the conviction of the bad luck that follows boasting.

The greatest happiness of life is the conviction that we are loved; loved for ourselves, or rather, loved in spite of ourselves.

The secret of success is conviction and persistence.

An irresistible passion that would induce me to believe in innate ideas and the truth of prophecy has decided my career. I have always loved liberty with the enthusiasm which actuates the religious man with the passion of a lover and with the conviction of a geometrician.

When the intensity of emotional conviction subsides, a man who is in the habit of reasoning will search for logical grounds in favor of the belief which he finds in himself.

A strong conviction that something must be done is the parent of many bad measures.

Everything an Indian does is in a circle, and that is because the power of the world always works in circles, and everything tries to be round. In the old days when we were a strong and happy people, all our power came to us from the sacred hoop of the nation, and so long as the hoop was unbroken the people flourished.

There is no failure except in no longer trying.

The planet does not need more “successful people.” The planet desperately needs more peacemakers, healers, restorers, storytellers and lovers of all kinds.

Without continual growth and progress, such words as improvement, achievement, and success have no meaning.

What I wanted was to be allowed to do the thing in the world that I did best, which I believed then and believe now, is the greatest privilege there is. When I did that, success found me.

To laugh often and much; to win the respect of intelligent people and the affection of children; to earn the appreciation of honest critics and endure the betrayal of false friends; to appreciate the beauty; to find the best in others; to leave the world a bit better, whether by a healthy child, a garden patch Or a redeemed social condition; to know even one life has breathed easier because you have lived. This is to have succeeded!
