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.

Life begets life. Energy creates energy. It is by spending oneself that one becomes rich.

Seek to do good, and you will find that happiness will run after you.

This is the true joy in life, the being used for a purpose recognized by yourself as a mighty one, the being thoroughly worn out before you are thrown on the scrap heap, the being a force of nature instead of a feverish little clod of ailments and grievances complaining that the world will not devote itself to making you happy.

The ready back gets all the loads.

The true way to soften one’s troubles is to solace those of others.

No one can sincerely try to help another without helping himself.

We cannot live only for ourselves. A thousand fibers connect us with our fellow-men; and along those fibers, as sympathetic threads, our actions run as causes, and they come back to us as effects.
