Life is the art of drawing without an eraser.

Having knowledge but lacking the power to express it clearly is no better than never having any ideas at all.

Even the knowledge of my own fallibility cannot keep me from making mistakes. Only when I fall do I get up again.

Knowledge is power. Information is liberating. Education is the premise of progress, in every society, in every family.

Knowledge is an unending adventure at the edge of uncertainty.

Our knowledge can only be finite, while our ignorance must necessarily be infinite.

Perplexity is the beginning of knowledge.

Without knowledge, action is useless, and knowledge without action is futile.

Happiness is not something ready-made. It comes from your own actions.

Just because something doesn't do what you planned it to do doesn't mean it's useless.

A champion is someone who gets up when he can't.

Knowledge will give you power, but character respect.

I try to learn from the past, but I plan for the future by focusing on the present exclusively. That's where the fun is

The end of all knowledge should be service to others.

You can find peace amidst the storms that threaten you.

Knowledge rests not upon truth alone, but upon error also.

I like to listen. I have learned a great deal from listening carefully. Most people never listen.

Knowledge is like money: to be of value, it must circulate, and in circulating, it can increase in quantity and, hopefully, in value.

The aim of education is the knowledge, not of facts, but of values.

No man's knowledge here can go beyond his experience.

Every addition to true knowledge is an addition to human power.

A man only learns in two ways, one by reading, and the other by association with smarter people.

The ability to perceive or think differently is more important than the knowledge gained.

Knowledge is in the end based on acknowledgement.

Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information on it.

Knowing is not enough; we must apply. Willing is not enough; we must do.

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

If you think you can do a thing or think you can't do a thing, you're right.
