Beliefs constitute the basic stratum, that which lies deepest, in the architecture of our life. By them we live, and by the same token we rarely think of them.... One may symbolize the individual life as a bank of issue. The bank lives on the credit of a gold reserve which is rarely seen, which lies at the bottom of metal coffers hidden in the vaults of the building. The most elementary caution will suggest that from time to time the effective condition of these guaranties--of these credences, one might say, that are the basis of credit--be passed in review.

Effort is only effort when it begins to hurt.

Living is a constant process of deciding what we are going to do.

We live at a time when man believes himself fabulously capable of creation, but he does not know what to create.

Life is a series of collisions with the future; it is not the sum of what we have been, but what we yearn to be.

And this is the simple truth - that to live is to feel oneself lost. He who accepts it has already begun to find himself to be on firm ground.

Tell me to what you pay attention and I will tell you who you are.
