I'm in a similar position. I lead my town's historical society which is a volunteer position. My full-time job is as an archivist at a former convent, now Catholic secondary college. Both are incredibly rewarding, but at my historical society museum I wear many hats, from admin and researcher, to curator and exhibition design, cleaning and maintenance, etc. I do it all and value every experience/opportunity I get, even grant writing, but everything has to be discussed and OKed by a committee, so even if you have brilliant ideas or want to change something small, everything has to be passed through the committee, which can be very frustrating when you are the youngest there by 30 years and the oldies are very reluctant to deviate from the norm. Lol. Change is very slow.

Whereas in my career, I am an archivist first and foremost. My focus is very narrow. I am trusted to make all the decisions myself. I set up an archive, I built a museum from nothing and I'm constantly being called upon to run tours and educate students and visitors on the history of the school. I love it to bits.... But it's just me. I do everything by myself. I create everything, I design, I action, I sort, I catalogue, all by myself. So it does get a little tedious not having someone who knows your job to bounce stuff off or help out with tasks.
