🎶 “Glimmers of Resilience” In our latest newsletter, we explored resilience from the lens of Virginia Blair, our Director of Marketing and Operations. And not just resilience, as a buzzword, but as a lived experience. One story stood out: a memory sparked by a Beatles song, a childhood car ride, and the lyric that became a lifelong mantra—“Nothing’s gonna change my world.”
Resilience doesn’t always look like powering through. Sometimes, it’s found in the quiet moments: a favorite song, a shared laugh, a memory that reminds us who we are. It’s in the “glimmers”—those small, joyful sparks that help us stay grounded, even when life feels uncertain.
As we close out Q3, we’re reflecting on the power of those glimmers—and how they help us show up stronger, together.
