Live as if you were living a second time, and as though you had acted wrongly the first time.

Man's search for meaning is the chief motivation of his life.

Ultimately, we are not subject to the conditions that confront us; rather, these conditions are subject to our decision ... we must decide whether we will face up or give in, whether or not we will let ourselves be determined by the conditions.

How can we dare to predict the behavior of man? We may predict the movements of a machine, of an automaton; more than this, we many even try to predict the mechanisms or "dynamisms" of the human psyche as well. But man is more than psyche.

What man actually needs is not a tensionless state but rather the striving and struggling for some goal worthy of him. What he needs is not the discharge of tension at any cost, but the call of a potential meaning waiting to be fulfilled by him.

Sleep [is like] a dove which has landed near one's hand and stays there as long as one does not pay any attention to it.

Man is not fully conditioned and determined but rather determines himself whether he gives in to conditions or stands up to them.
