Yes I do! I wanted a writing partner for so long because writing is so hard and sometimes lonely. I’ve learned it’s rare to find someone you click with, so first piece of advice: don’t be afraid to write on your own.
That being said since you have a partner, I had a great experience writing a pilot with a friend. Before we committed to the pilot we had been in a sketch group together so I new her writing style and we had gotten pretty comfortable working together that way so it was an easy transition.
I’d just say try to get to a place where you and your partner can be as honest with each other about the writing as possible. You both want it to be good so know that that’s what you are after so disagreements or notes on each other’s writing come from a good place.
Hope that helps. LMK if you have a more specific question about partner writing:)
