 Two that come to mind, and to be fair, all the virtues are for everybody. But patience and humility come to my mind because I think it's so hard. And I don't say this because I think teens should be lectured about patience. Virtues are meant to dispose us to happiness. That's the thing that I think we get lost a lot of times in this conversation. The moral life is the happy life. So we're wanting to help children practice this disposition towards the good, this virtuous disposition.
