Two things I think me and Matthew did well were 1. We both had an open mind and listened to each others ideas. 2. I also think we did a good job of distributing the work evenly between us and dividing and conquering.
One thing I want to do better going forward is talk a little more and not just listen. I feel like I keep an open mind and share some ideas but it is also important to actually add stuff and not just listen and agree even when I may not the whole time.
