My son may also lead men someday, although his domain will be in Midgard and his power nowhere near as great.
He learns from his father, from his strengths and his weaknesses, he makes mistakes and he knows not to make them again, he sees how others use power and makes his judgement on them, which guides him when he is in the same position.
But he also learns from you, from your father, from Loki the trickster and Frigg the wise, from Freya the fierce and Baldr the beautiful. He learns from your strengths and your weaknesses, just as he does his own father. Therefore you cannot fail him and all those like him, no matter what you do.
