When I got my library card, that's when my life began.

Brown frames the library card as a threshold object: a small credential that grants entry to a vast public commons of knowledge, stories, and self-invention. The line suggests that for a curious child—especially one who may feel constrained by family, class, geography, or social expectations—books can function as a first form of autonomy. “My life began” is deliberate hyperbole, emphasizing how reading can awaken identity, ambition, and a sense of possibility. The quote also implicitly defends libraries as democratic institutions: life-changing not through luxury, but through free access to ideas and imagination.
