Happiness is the final and perfect fruit of obedience to the laws of life.

A person who is severely impaired never knows his hidden sources of strength until he is treated like a normal human being and encouraged to shape his own life.

I don't give a damn about semi-radicals!

What I am looking for is not out there, it is in me.

If I am happy in spite of my deprivations, if my happiness is so deep that it is a faith, so thoughtful that it becomes a philosophy of life. If, in short, I am an optimist, my testimony to the creed of optimism is worth hearing.

It is so pleasant to learn about new things. Every day I find how little I know, but I do not feel discouraged since God has given me an eternity in which to learn more.

There is no blindness more insidious, more fatal that this race for profit.
