Education is for freedom - freedom from mental slavery.

The most painful moment in my life also became the moment I showed the most strength and courage.

My mind, he said, rebels at stagnation. Give me problems, give me work, give me the most abstruse cryptogram or the most intricate analysis, and I am in my own proper atmosphere. I can dispense then with artificial stimulants. But I abhor the dull routine of existence. I crave for mental exaltation. That is why I have chosen my own particular profession, or rather created it, for I am the only one in the world.

I have never met a mentally strong person who wasn't a voracious reader.
