“The happiness of your life depends upon the quality of your thoughts.”
“Very little is needed to make a happy life; it is all within yourself in your way of thinking.”
“The things you think about determine the quality of your mind. Your soul takes on the color of your thoughts.”
“There is only one way to happiness and that is to cease worrying about things which are beyond the power or our will.”
“Unhappy am I because this has happened to me. Not so, but happy am I, though this has happened to me, because I continue free from pain, neither crushed by the present nor fearing the future.”
“Man is not worried by real problems so much as by his imagined anxieties about real problems.”
“Remember from now on whenever something tends to make you unhappy, draw on this principle: 'This is no misfortune; but bearing with it bravely is a blessing.”
“When you are feeling upset, angry, or sad, don’t blame another for your state of mind. Your condition is the result of your own opinions and interpretations.”
“True happiness is to enjoy the present, without anxious dependence upon the future, not to amuse ourselves with either hopes or fears but to rest satisfied with what we have, which is sufficient, for he that is so wants nothing.”
“People with a strong physical constitution can tolerate extremes of hot and cold; people of strong mental health can handle anger, grief, joy and the other emotions.”
