Albert Schweitzer

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

"Think with great gratitude of those who have lighted the flame within us."

"At times, our own light goes out and is rekindled by a spark from another person. Each of us has cause to think with deep gratitude of those who have lighted the flame within us."

"Train yourself never to put off the word or action for the expression of gratitude."

"Example is not the main thing in influencing others. It is the only thing."
