I feel you and working as a teacher, sometimes it isn’t about what unique viewpoints you bring to the table, but rather about how you can express done-to-death stuff in your own way. I still get amazed by my students’ sparks of brilliance (admittedly few and far between) in their compositions

I wanted to write a book at the intersection of theology and economics, but it's a fairly crowded space.  I'm not entirely sure I have something unique to say.
