It's not enough to be kind. One should be kinder than needed. Why I love that line, that concept, is that it reminds me that we carry with us, as human beings, not just the capacity to be kind, but the very choice of kindness. And what does that mean? How is that measured? You can't use a yardstick. It's like I was saying just before: it's not like measuring how much you've grown in a year. It's not exactly quantifiable, is it?
