A watershed (noun) is a divide or, more specifically, a region or area bounded peripherally by a divide and draining ultimately into a particular watercourse or body of water. This is used to describe a crucial dividing point, line or factor; a turning point. A watershed moment.
Always, I've found, that coming to see Michelle divides little epochs in my life. The last time I was here, I had the spark of inspiration for a novel. This time, I am learning to test the waters of a writer-in-the-world. This is the point where things have come into total clarity (or near-total clarity), and I cannot go back to the former way of thinking about graduate school or how it relates to my worth as a writer. I am in watershed days now, and I am excited to see what pool these waters eventually fill.
