Something I just started trying is to repeat to myself in my mind what they're saying to me in real time. Like, as they're talking, I'll think the words they're saying to kind of reinforce their message. I'll do it when I notice I'm losing focus or getting anxious. I'll also do square breathing with a very slow out breath. If I focus on my breath, their words just kind of sink in as they're talking. Sometimes I'll ask them to repeat themselves if I really zone out (I have ADHD and I'm also hearing impaired lol.)
