He slammed the lid of his laptop shut, a wide smile splitting his face. The email. He’d reread it three times, just to be sure. His rambling, late-night application essay on the existential dread of grocery shopping had been selected for a university pamphlet. A pang of initial embarrassment had quickly transformed into something else entirely.

A sudden need to move, to *do*, washed over him. He stood up abruptly, pacing the cramped confines of his dorm room. The stale air felt thick, confining. Grabbing his coat, he burst out the door, the chill of the morning air hitting him like a physical challenge. He felt like he could run a marathon.

The campus, usually a mundane backdrop to his day, now shimmered with possibilities. He texted his friend, proposing a spontaneous hike. He was ready to seize the day.
