There is no duty we so much underrate as the duty of being happy.

The habit of being happy enables one to be freed, or largely freed, from the domination of outward conditions.

Quiet minds cannot be perplexed or frightened but go on in fortune or misfortune at their own private pace, like a clock during a thunderstorm.

When your toil has been a pleasure, you have not earned money merely, but money, health, delight, and moral profit, all in one.

Every heart that has beat strongly and cheerfully has left a hopeful impulse behind it in the world, and bettered the tradition of mankind.

The world is so full of a number of things, I'm sure we should all be as happy as kings.

To be truly happy is a question of how we begin, and not how we end, of what we want and not what we have.

In every part and corner of our life, to lose oneself is to be a gainer; to forget oneself is to be happy.

Make up your mind to be happy. Learn to find pleasure in simple things.
