One can choose one's attitude in any given set of circumstances.

Each man is questioned by life; and he can only answer to life by answering for his own life; to life he can only respond by being responsible.

What will it matter to him if he notices that he is growing old? Has he any reason to envy the young people whom he sees, or wax nostalgic over his own lost youth? What reasons has he to envy a young person? For the possibilities that a young person has, the future which is in store for him? "No, thank you," he will think. "Instead of possibilities, I have realities in my past, not only the reality of work done and love loved, but of sufferings bravely suffered. These sufferings are even the things of which I am most proud, though these things are things that cannot inspire envy."

When we are no longer able to change a situation - we are challenged to change ourselves.

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

It did not really matter what we expected from life, but rather what life expected from us. We needed to stop asking about the meaning of life, and instead to think of ourselves as those who were being questioned by life—daily and hourly. Our answer must consist, not in talk and meditation, but in right action and in right conduct. Life ultimately means taking the responsibility to find the right answer to its problems and to fulfill the tasks which it constantly sets for each individual.

Life is not primarily a quest for pleasure, as Freud believed, or a quest for power, as Alfred Adler taught, but a quest for meaning. The greatest task for any person is to find meaning in his or her own life.
