“The most mentally deranged people are certainly those who see in others indications of insanity they do not notice in themselves.”

“The happiest people are those who think the most interesting thoughts. Those who decide to use leisure as a means of mental development, who love good music, good books, good pictures, good company, good conversation, are the happiest people in the world. And they are not only happy in themselves, they are the cause of happiness in others.”

“The happiest people are those who do the most for others. The most miserable are those who do the least.”

“Generally speaking, the most miserable people I know are those who are obsessed with themselves; the happiest people I know are those who lose themselves in the service of others...By and large, I have come to see that if we complain about life, it is because we are thinking only of ourselves.”

“Do not think about guys who have broken your heart six ways. It is mentally deranged to chase after heartbreak.”

“The most silent people are generally those who think most highly of themselves.”
