I don't have advice either way. I do think it's very reasonable to go in with a specific agenda and stick to that, especially since you might not see a third-stringer ever again. I also think it could be a good exercise to have your own mental health hour, to set aside that time (plus the travel time) to do something that you think will help you feel like your best self (art, journaling, yoga, go for a walk, read a mental health book or do some research into something etc). Hopefully you can make something good out of the time regardless of what you do.
