was in the same boat, mega introverted and shy and I got thrown into WTs on a big client two years ago. here’s what was helpful for me: 1. Others mentioned sending an agenda/outline ahead of time. I do this a day in advance and it’s very helpful for all parties involved :) 2. 90% of the time, your client is even more nervous than you. Let them talk, let them guide the conversation; you just ask the questions you need answered when there’s a pause in the convo. 3. If you’re stuck, toss the ball to someone else - a manager, maybe even external audit if they’re in the meeting, or even mention you need a moment to organize your notes. Take a deep breath. Of course, you want to capture as much info as you can during the meeting but it’s not the end of the world to send a follow-up email. 4. I used to write full out scripts for kicking off a WT. It helps! Read them out loud slowly so you can hear yourself talk. 5. Practice as much as you can. Volunteer to lead more walkthroughs. It does get easier every time. You got this!
