Mentors come in all forms, shapes, and sizes and communicate in uniquely diverse ways. I’ve been fortunate to have several mentors who have shaped my life—from the profoundly eloquent and sharp, to the rambling, and tangential, and even the completely silent. When I was in college, I had a professor named Mike. Professor Mike (who is still teaching) taught Fluvial Geomorphology—the dynamics of how rivers and lakes change and evolve over time, on their own. He was the kind of teacher who was more of a person than a professor and treated students like peers, rather than pupils.
