I spent most of today on the campus of St. Paul's School in Concord, New Hampshire. My time there was filled with waves of nostalgia, as SPS was where I spent my most formative summer. This was where I started teaching after my junior year in college, the place I discovered what I wanted to do with the rest of my life. I was 20 years old and experiencing a prep school for the very first time. I was lucky to meet my mentor, work with a terrific group of kids, and given the chance to teach, to coach, to supervise a dormitory--things I've spent a fair bit of my life doing ever since.
