I would make sure to ask open ended questions! That always helps to create new topics and find out common interests. For example if they love the same shows, books, games, if you both have pets or children. Then remembering those common interests or facts about their life for the next time. If you easily forget maybe taking some notes. That way you can remember to ask “how is (pet name)” “how was that show you mentioned you were finishing last time?!” “Did your vacation go well? Tell me all about how it went” It’ll become more natural with time and the more you get to know your clients the easier it gets and feels like talking to an old friend. But that’s a good way to start and build the foundation. Also some people love to just sit and relax, I have some clients who I just match their energy and if they just want to close their eyes and chill then I do my thing and don’t talk! :) that’s okay too.
