Theodore Roosevelt: "Comparison is the thief of joy."

Happiness is not something ready-made. It comes from your own actions.

The purpose of life is to live it, to taste experience to the utmost, to reach out eagerly and without fear for newer and richer experience.

Count your age by friends, not years. Count your life by smiles, not tears.

The most important thing is to enjoy your life — to be happy. It's all that matters.

Joy is not in things; it is in us.

Happiness is when what you think, what you say, and what you do are in harmony.
