Movies and TV Shows

As I've progressed and gotten more and more specialized in my field, I may not have anyone else "ahead" of me anymore, but there are still plenty of other people that have specialized in different ways, both in my field more generally, in their own niche, and outside the field entirely. I think so long as you engage with people who keep learning and specializing, people who have empathy and can show understanding, you're never really short of peers. You'd be surprised at how others' experience, even in radically different fields, can shape new insights and cause you to grow as a professional and a person. Breadth of knowledge gives you more tools to solve problems creatively.
