"Who will teach the young wisdom and discipline? "
Wisdom is not taught, systems are taught. Wisdom comes from experiencing life, or it never comes at all. And life is its own discipline.
"What produces growth and progress? "

It is the going out from oneself that is love and not the accident of its return. It is the expedition, whether it fail or succeed.
