" One may be strengthened & fed without the aid of Joy, & no one knows it better than I do; & I believe I know the only cure, which is to make one’s center of life inside of one’s self, not selfishly or excludingly, but with a kind of unassailable serenity—to decorate one’s inner house so richly that one is content there, glad to welcome anyone who wants to come and stay, but happy all the same when one is inevitably alone. "

― Edith Wharton ,
