As tough as things have been, I am convinced you are tougher. I've seen your passion and I've seen your service. I've seen you engage and I've seen you turn out in record numbers. I've heard your voices amplified by creativity and a digital fluency that those of us in older generations can barely comprehend. I've seen a generation eager, impatient even, to step into the rushing waters of history and change its course.
