“Pay no attention to the smartest, the prettiest, the richest, the most refined person you know. Welcome to your heart only the one who has kindness in his soul. All the rest of them, if they are not kind people in addition to what they are, at some point will harm you, putting their personal interest above all, crushing any part of your soul it does not suit them for you to have, turning any serenity of yours into a cage full of destructive storms.”
