Building a diverse team and enabling them to be successful inside an overall-less-diverse organization has a lot in common with activism. And I think it's subject to the same sort of burnout that you see in the activism community.
Take care. It's hard to recognize that you're constantly over capacity if it gives you the extra kick to do what you do. In my case it ended in heart surgery... an experience I don't wish on anybody, although it gave me insight on how my father must have felt when he had his.
