“Very little is needed to make a happy life; it is all within yourself in your way of thinking.”
“It's not what happens to you, but how you react to it that matters.”
“The happiness of your life depends upon the quality of your thoughts: therefore, guard accordingly, and take care that you entertain no notions unsuitable to virtue and reasonable nature.”
“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.”
“We are not disturbed by what happens to us, but by our thoughts about what happens to us.”
“There is only one way to happiness and that is to cease worrying about things which are beyond the power or our will.”
“Don't seek to have events happen as you wish, but wish them to happen as they do happen, and all will be well with you.”
“The happiness of those who want to be popular depends on others; the happiness of those who seek pleasure fluctuates with moods outside their control; but the happiness of the wise grows out of their own free acts.”
“He who laughs at himself never runs out of things to laugh at.”
