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.
