The only part of the conduct of any one, for which he is amenable to society, is that which concerns others. In the part which merely concerns himself, his independence is, of right, absolute. Over himself, over his own body and mind, the individual is sovereign. – John Stuart Mill
And we should consider every day lost on which we have not danced at least once. And we should call every truth false which was not accompanied by at least one laugh. – Friedrich Nietzsche
