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.

Don’t cry because it’s over. Smile because it happened.

Tell me and I forget. Teach me and I remember. Involve me and I learn.

Experience is not what happens to you; it’s what you do with what happens to you.

Experience is simply the name we give our mistakes.

In three words I can sum up everything I’ve learned about life: it goes on.

Character cannot be developed in ease and quiet. Only through experience of trial and suffering can the soul be strengthened, ambition inspired, and success achieved.

Live as if you were to die tomorrow. Learn as if you were to live forever.

I am always doing that which I cannot do, in order that I may learn how to do it.

I don’t like people who have never fallen or stumbled. Their virtue is lifeless and it isn’t of much value. Life hasn’t revealed its beauty to them.

It is what we know already that often prevents us from learning.

Experience, if we only learn by it, is cheap at any price.

Research your own experience. Absorb what is useful, reject what is useless, and add what is specifically your own.

Experience is a great spoiler of pleasures.

No good decision was ever made in a swivel chair.

But the world itself has no reason, and I can say so, I who have experienced it all, from the creation to the destruction.

Life is short, art long, opportunity fleeting, experiment uncertain, and judgment difficult.

Life is the only real counselor; wisdom unfiltered through personal experience does not become a part of the moral tissue.

It’s what you learn after you know it all that counts.

In wisdom gathered over time I have found that every experience is a form of exploration.

All our thoughts and concepts are called up by sense-experiences and have a meaning only in reference to these sense-experiences. On the other hand, however, they are products of the spontaneous activity of our minds; they are thus in no wise logical consequences of the contents of these sense-experiences. If, therefore, we wish to grasp the essence of a complex of abstract notions we must for the one part investigate the mutual relationships between the concepts and the assertions made about them; for the other, we must investigate how they are related to the experiences.

Nothing is a waste of time if you use the experience wisely.

Obviously an actor draws on his own experience.

Life will give you whatever experience is most helpful for the evolution of your consciousness.

All that I know I learned after I was thirty.

Eyes that have never wept cannot comprehend sorrow.

Science is the systematic classification of experience.

The less there is of you, the more you experience the sublime.

Everything depends on how relentlessly one forces from experience the last drop, sweet or bitter, it can possibly give.

I wish the days to be as centuries, loaded, fragrant. Now we reckon them as bank-days, by some debt which is to be paid us, or which we are to pay, or some pleasure we are to taste.

You can’t be brave if you’ve only had wonderful things happen to you.

There is no wider gulf in the universe than yawns between those on the hither and thither side of vital experience.

Take your work seriously but never take yourself seriously and do not take what happens either to yourself or your work seriously.

The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn, and relearn.

To be happy in this world, especially when youth is past, it is necessary to feel oneself not merely an isolated individual whose day will soon be over, but part of the stream of life flowing on from the first germ to the remote and unknown future.
