One could imagine a yin book about agency, called Don't Just Do Things. It would include topics like how to attend to the system you're a part of rather than pursuing your individual agenda, how to be patient until an intuitive solution arises naturally, and how to submit gracefully to the existing forces of change in your life rather than pushing, pushing, pushing. The book's message would be that the search for an optimal choice, for better, sometimes causes us to foolishly overlook the possibility of skillfully, gently flowing with the momentum of what is already going to happen, of being receptive to our current character rather than trying to change it.
