Justin Guarini’s “Center Stage Confidence” offers professionals a practical framework based on 20 years of experience to communicate with confidence.
NEW YORK, NY, UNITED STATES, September 22, 2026 /EINPresswire.com/ — Justin Guarini, the “American Idol” runner-up in the show’s first season, a seven-time Broadway leading man, the voice of “Cat Burglar” in Disney Junior’s “SuperKitties,” and the longtime face of Diet Dr Pepper’s national “Lil’ Sweet” campaign, shows readers how to own their story, step forward before they feel ready, and command any room in his new book, now available for pre-order through retailers everywhere.
In “Center Stage Confidence: How to Own Your Story and Command Any Room,” Guarini reveals how to transform pressure into presence through practical exercises designed to deliver a real-world return to clarity, influence, and opportunity for readers.
“The idea for this book didn’t just come from my successes,” writes Guarini, who is also cofounder of Powerful Professionals, a coaching organization for eight and nine-figure entrepreneurs and experts.
“It came from my failures — the moments when I doubted myself, when I let fear hold me back, or when I felt like I wasn’t enough.”
“Center Stage Confidence,” published by Entrepreneur Press and distributed by Simon & Schuster, is scheduled for release Oct. 6. The book is aimed at professionals who go silent in meetings, lose their words in front of an audience, or hold themselves back from opportunities they have already earned. Drawing on the mindset shifts behind Guarini’s career performing under pressure, the book helps readers develop the confidence to step fully into those opportunities and transform their businesses and lives.
Throughout “Center Stage Confidence,” Guarini draws on his experiences in music, television, Broadway and business while featuring candid conversations with celebrated performers and entrepreneurs, including Michael Bublé, Jordan Fisher, Amber Ruffin, Kim Walsh Phillips and Russell Brunson. Together, they explore the habits, failures, and defining moments that helped them thrive under pressure.
For Guarini, taking center stage isn’t just about chasing dreams or commanding attention.
“It’s about showing up fully — for yourself, your loved ones, and the moments that matter,” he writes. “It’s about owning your story, even the uncomfortable parts, and using it to inspire others to own theirs.”
