Do not wait for leaders; do it alone, person to person.

Think that day lost whose descending sun, views from they hand no noble action done.

Anything you can do needs to be done, so pick up the tool of your choice and get started.

Such to me is the new image of aging: growth in self and service for all mankind.

It is the duty of youth to bring its fresh powers to bear on Social progress. Each generation of young people should be to the world like a vast reserve force to a tired army. They should lift the world forward. That is what they are for.

How should one live? Live Welcoming to all.

If you live only for yourself, you are always in immediate danger of being bored to death with the repetition of your own views and interests.

The only truly happy man is always a fighting optimist. Optimism includes not only altruism but also social responsibility, social courage and objectivity.

Unless we think of others and do something for them, we miss one of the greatest sources of happiness.

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.
