Small spaces fit big ideas. Consider the middle-school locker. Though merely 1.5 cubic feet, it offers its tenant an address, a front door, a home. She decorates, taping up selfie, groupie, fan photo: me, my squad, my dreams.

She repeats this exercise in camp bunk, dorm room and short-term sublet, its shelves full of empties, kitchen a communal clutter, bedroom the size of bed. She tacks up mirror, map and pushpins: Me, on my way.

She stops in the big city, where a big-name chef has compressed his talents into a tiny, tasty takeout. Small space. Big ideas. One bite, and she feels right at home.
