I’m thrilled to read your post and the plethora of responses by people who resonate with it. In fact, I’m almost finished writing a book on this topic. It’s titled “More than my title” and it’s about the phenomenon that people have multiple professional identities. Importantly, when people combine or crossover their professional identities, they create hybrid identities which is where our best talent and highest abilities and performance reside. I’ve been studying this topic for a few years, and the responses from these posts correlate with my findings. Follow my work on the book at www.sarabethberk.com
