“No one has less serenity than the person who does not know what is right or wrong. No one is more exhausted than the person who, because they lack a moral code, must belabor every decision and consider every temptation. No one feels worse about themselves than the cheater or the liar, even if—often especially if—they are showered with rewards for their cheating and lying. Life is meaningless to the person who decides their choices have no meaning.”

Ryan Holiday, Stillness is the Key (Page 99)
