The sole meaning of life is to serve humanity.

For what purpose humanity is there should not even concern us: why you are here, that you should ask yourself: and if you have no ready answer, then set for yourself goals, high and noble goals, and perish in pursuit of them!

Life is certainly only worthwhile as it represents struggle for worthy causes. There is no struggle in perfect security. I am quite certain that the human being could not continue to exist if he or she had perfect security.

We defend and we build a way of life, not for America alone, but for all mankind.

In order to lead a meaningful life, you need to cherish others, pay attention to human values and try to cultivate inner peace.

We are visitors on this planet. We are here for one hundred years at the very most. During that period we must try to do something good, something useful, with our lives. if you contribute to other people's happiness, you will find the true meaning of life.
