In youth we learn; in age we understand.

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

Question everything. Learn something. Answer nothing.

I learned the value of hard work by working hard.

There is no end to education. It is not that you read a book, pass an examination, and finish with education. The whole of life, from the moment you are born to the moment you die, is a process of learning.

Education is what remains after one has forgotten what one has learned in school.

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.

Study nature, love nature, stay close to nature. It will never fail you.
