"Happiness is like the rainbows of life... Rainbows aren't real. You can't walk up and touch one. It's a trick of light. That doesn't mean you've never seen one. And I bet every time it's happened, you smiled."

"I absolutely think that happiness is a choice. One of the most potent forces in human psychology is the power of habit. Do something, think something, often enough and it will become the only thing you can do or think. Choose to be unhappy and soon that’s all you will be. Live in a swamp and you’ll grow webbed feet."

"Have a variety of interests. ... These interests relax the mind and lessen tension on the nervous system. People with many interests live not only longest but happiest."

"A thorn in your side will drive you to find someone or thing to remove it. Therefore, don't hate your enemies. Thank them. Without them, you wouldn't have traveled as far in your life to find peace and happiness."
