Resilient Optimism

The Science of Sustaining a Positive Mindset in Tough Times

Harvard Business Review Press, September 2026



It’s easy to start with optimism—at the beginning of a project, a sports season, a marriage, during a winning streak, when energy is high.



The real challenge is sustaining it when pressure builds, setbacks stack up, and life doesn’t let up.



Resilient Optimism shares the science behind why optimism so often fades under stress—and what actually helps it endure. Drawing on decades of research in positive psychology and neuroscience, Michelle Gielan shows that optimism isn’t about forced positivity or ignoring reality. It’s a trainable skill, built through simple, repeatable habits that stabilize mindset and performance when things get hard.



Practical, research-backed, and deeply human, this book offers a clear path to staying energized, focused, and effective—at work and in life—especially when it matters most.

For leaders, teams, parents, and anyone who wants to create positive change, Broadcasting Happiness offers a clear message: when you change what you broadcast, you change what’s possible—for yourself and for everyone around you.
