Knox smiles. "There is no such thing as 'too many questions.' OK, maybe you can ask the wrong ones, but my whole life depends on always asking the right ones. And on not being afraid to ask.

"Just sometimes, you need to ask the right person. But if you are going to get an education, you can't let me stop you." Knox has never regretted not going to college. But he does wish he could help more with things he never learned.
