“Happiness is not a matter of events, it depends upon the tides of the mind.”
“Happiness depends more upon the internal frame of a person’s own mind, than on the externals in the world.”
“Happiness depends upon ourselves.”
“Remember, happiness doesn't depend upon who you are or what you have, it depends solely upon what you think.”
“Happiness, as is evident, depends partly upon external circumstances and partly upon oneself.”
“The greater part of our happiness or misery depends upon our dispositions, and not upon our circumstances.”
