I always made sure to make a personal connection at least once without losing the structure of the hour. For instance I would remember something about the family (or pets, or work) and ask about it. Or mention a point he made last week that you revisited, such as, “I thought about that point you made…” or “I was learning how to do X and it made me think of you starting from scratch on this topic” etc. give him value, and that will give you and your time together a positive feeling.
