“People are not disturbed by things, but by the views they take of them.”
“Man is not worried by real problems so much as by his imagined anxieties about real problems.”
“Freedom is secured not by the fulfilling of one's desires, but by the removal of desire.”
“Make the best use of what is in your power, and take the rest as it happens.”
