There is no value in life except what you choose to place upon it and no happiness in any place except what you bring to it yourself.

The man who makes everything that leads to happiness depends upon himself, and not upon other men, has adopted the very best plan for living happily. This is the man of moderation, the man of manly character and of wisdom.

The only thing that could spoil a day was people. People were always the limiters of happiness except for the very few that were as good as spring itself.

Money won't buy happiness, but it will pay the salaries of a large research staff to study the problem.

To find out what one is fitted to do, and to secure an opportunity to do it, is the key to happiness.

Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful.

Happiness is neither virtue nor pleasure nor this thing nor that but simply growth, We are happy when we are growing.

The smallest seed of faith is better than the largest fruit of happiness.

Happiness does not come from doing easy work but from the afterglow of satisfaction that comes after the achievement of a difficult task that demanded our best.

I would maintain that thanks are the highest form of thought, and that gratitude is happiness doubled by wonder.
