"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."
"Most of us have far more courage than we ever dreamed we possessed."
"you can measure the size of a person by what makes him or her angry"
"Men of age object too much, consult too long, adventure too little, repent too soon, and seldom drive business home to the full period, but content themselves with a mediocrity of success."
"Be wiser than other people if you can; but do not tell them so."
