The other day my nephew came up to me (about eight years old) and said, "Uncle Ben, when I grow up I want to be just like you.
I was so awed and overwhelmed and I hugged him and said, "Oh sweetie... And I had such high hopes for you."
as long as he is happy it doesn't matter what he does. anyway, at 8 years old there is a good chance he will change his mind.
