The necessary thing for anyone to be happy and contented as long as he lives is working for the ones who will come after him rather than working for himself... One can reach the true delight and happiness in the life only by working for the existence, honor, and happiness of the future generations.

Those who are not looking for happiness are the most likely to find it, because those who are searching forget that the surest way to be happy is to seek happiness for others.

The happiest moments we ever know are when we entirely forget ourselves.

If you want to live a happy life, tie it to a goal, not to people or things.

Those who serve supreme causes must not consider what they can get but what they can give.

There can be no greater gift than that of giving one's time and energy to help others without expecting anything in return.
