Open source and community project maintainers (and contributors) need to work hard on patience, empathy, and humility. It was something that took me a while, and even now after ~20+ years in the space, I can fail at those values at times. I know I've not always been the best at these things, and I still strive to learn.

Arrogance is neither sexy or cool. You need to meet people where they area, and show up, sometimes even in person. One of the reasons that I've valued meetups and events.
