Our greatest freedom is the freedom to choose our attitude.

Man's inner strength may raise him above his outward fate.

It is the pursuit of happiness that thwarts happiness.

I understood how a man who has nothing left in this world may still know bliss, be it only for a brief moment, in the contemplation of his beloved. In a position of utter desolation, when a man cannot express himself in positive action, when his only achievement may consist in enduring his sufferings in the right way - an honorable way - in such a position man can, through loving contemplation of the image he carries of his beloved, achieve fulfillment.

Man is not fully conditioned and determined but rather determines himself whether he gives in to conditions or stands up to them. In other words, man is ultimately self-determining. Man does not simply exist but always decides what his existence will be, what he will become in the next moment.

Fear may come true that which one is afraid of.

For the world is in a bad state, but everything will become still worse unless each of us does his best.
