The last freedom is choosing your attitude.

Ironically enough, in the same way that fear brings to pass what one is afraid of, likewise a forced intention makes impossible what one forcibly wishes... Pleasure is, and must remain, a side-effect or by-product, and is destroyed and spoiled to the degree to which it is made a goal in itself.

A sound philosophy of life, I think, may be the most valuable asset for a psychiatrist to have when he is treating a patient.

Man can only find meaning for his existence in something outside himself.

Love goes very far beyond the physical person of the beloved. It finds its deepest meaning in its spiritual being, his inner self. Whether or not he is actually present, whether or not he is still alive at all, ceases somehow to be of importance.

You don't create your mission in life - you detect it.

Self-actualization cannot be attained if it is made an end in itself, but only as a side effect of self-transcendence.
