It sounds like a dream of his. In MLC, they dream of places that they want to go to and experience. If he's planning to work an additional ten years, this dream may not happen at all. I would just listen and nod my head because he may very well change his mind in another 6 months. Ten years is a long time away and who knows what may happen within that time span.
Focus on today and let the future unfold. There is no sense in being concerned about something that may or may not happen in ten years. Keep the focus on you.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
