In short, I wish more people had empathy for open-source maintainers and tried to understand things from their point of view. I wrote this post to try to articulate my own feelings as I began to spiral towards my own burnout: https://nolanlawson.com/2017/03/05/what-it-feels-like-to-be-an-open-source-maintainer/
After I wrote that post, I was contacted by dozens of open-source maintainers who told me I captured exactly how they felt. So hopefully it stands as a good insight for anyone trying to understand the mind of an open-source maintainer.
