Back in May 2007, my first chalk talk was immortalized on a grainy VHS tape—a true time capsule of early grad school awkwardness. I showed up in cargo shorts with my dress shirt inexplicably tucked in, a yellow Livestrong bracelet on one wrist, and a watch I couldn’t stop tugging at. Between the fidgeting, the questionable outfit, and the shaky delivery, it was far from polished. But it was mine, and like every clumsy beginning, it marked the start of something bigger.
