Then grab that 1:1 attitude and run with it. You're talking about your favorite topic to just one person who is intensely interested in what you have to say, and will rarely interrupt you. This is where introverts excel, so be in that mental state. 1:1. Embrace it. And embrace the notion that just because that one intensely interested person is manifested as 2, or 10, or 100, or 10,000 makes absolutely no difference.
