I wouldn't recommend what I do, but I'll put it out there since it works for me. The more I prep, the more I worry about it. The more I try to perfect everything, and get in my own head about every detail, every stutter, and it all backfires 99% of the time. So, what do I do? I hardly prep at all. I go in just going to have a conversation with someone. If they have questions, I've likely already experienced something similar during my time in the field so I'll just talk about that. The more I can prevent myself from putting everything on a pedestal, the less I stutter. It's very much tied to my anxiety. Some of the ability to talk from experience does come from being in my field for a while now though. Again, not recommending this necessarily, but it does work for me. I don't prep at all, I don't practice, and I feel super comfortable. I don't even think twice about it anymore. Again, the less I spend time building it up in my head, the better.
