Composure
Composure is something that I tend to have a great sense of during both gameplay and development. I'm one of those people who thrive off of controlled chaos, so when my players are panicking, I'm smiling on the sidelines. There are GMs out there who aim to punish or hurt their players, even going to the extent of a TPK, but I'm not one of them. The reason I'm smiling is because I enjoy seeing the gears turn, the troubleshooting chats shared between them, and the reasoning they come up with. Seriously, sometimes they get really creative and it impresses the hell out of me. In fact, sometimes they come up with wild ideas that derail most if not all of my prepped plans. During my first homebrew campaign with my current group (utilizing D&D 3.0/3.5 rules), they were really adamant about going down one particular route. I didn't have the map prepared at all because I honestly expected them to pass it by, go back to town for preparation, THEN go back out and get to that map. No, they didn't do any of that. In fact, they bypassed a lot of things and immediately went straight for it. I had to MS Paint the images on the fly, and they gave me a good ribbing for it for months on end. To this day they still mention it from time to time, generally when I'm discussing my progress in preparing sessions. If I didn't have my composure set for that session, I would never have been able to continue it.
As for a game dev perspective, I'm usually cool as a cucumber. When I work on my modules and systems in FoundryVTT, I get to see my playtesters' honest reactions to what I've created. If something doesn't work like intended (which does happen), I try my best to fix it right then and there. Sometimes that doesn't fix the problem, which then turns into an issue I need to solve. Active testing of what I'm building is genuinely one of the finer things in life.
Keeping your composure during the best of times and worst of times can be rewarding.
