"Most of us have far more courage than we ever dreamed we possessed."

"Be wiser than other people if you can; but do not tell them so."

"People rarely succeed unless they have fun in what they are doing."

"Remember, happiness doesn't depend upon who you are or what you have; it depends solely upon what you think. So start each day by thinking of all the things you have to be thankful for. Your future will depend very largely on the thoughts you think today. So think thoughts of hope and confidence and love and success."

"It isn't what you have, or who you are, or where you are, or what you are doing that makes you happy or unhappy. It is what you think about."
