Erich: So, as I am driving to class, I always ask inwardly for guidance about what to talk about. "If there is anything to talk about, what should I talk about?" That is the question I say. That way I am not assuming that I am going to have to talk about something, or that there will be a talk, or that I really know what's up. But, "If I am supposed to talk about something, what should I talk about today?" I Google it!
Remember, that's the practice. That's the thing to do.
