@DavidKnuffke definitely a word I think about often and I definitely agree that a word like leader like a few others is best left for others to call someone. I know I might be a leader in something when others call me that.
I also think about "leadership positions" and how some people who hold them are not people that I would characterize as "leaders" at all. I am mindful of the Peter principle, the lack of leadership training many receive, nepotism, privilege, and that many "leaders" are managers.
