When I find someone's advice or input useful, it can be tempting to think I'm dependent on them. This is incorrect. If their advice or input is useful, they almost certainly did not generate it themselves but simply have access to a large body of learnings and experience. I'm dependent on the database, but not on the interface. The person is the interface. Interfaces come and go; the database is impersonal. It's the aggregate of God's wisdom. So I see through the interface to what lies beyond and recognise that this person is merely the current method of accessing that database.
