Resilient Optimism

I found Michelle Gielan’s 'Resilient Optimism: The Science of Sustaining a Positive Mindset in Tough Times' hard to put down. It’s wise, compassionate and thoroughly practical.

Gielan is a positive psychology researcher and speaker. She was an executive producer of The Happiness Advantage on PBS and is a featured professor in Oprah’s Happiness course. She’s also the bestselling author of Broadcasting Happiness: The Science of Igniting and Sustaining Positive Change.

In the first chapter of Resilient Optimism, Gielan references a pair of studies published in Harvard Business Review that she did with Arianna Huffington. In the first, a group of participants was exposed to three minutes of negative news and a control group to three minutes of neutral news. Six to eight hours later, participants who had seen the negative news were 27 percent more likely than the control group to say that they’d had a negative day.

In a follow-up study, half of the participants were given a short list of possible solutions alongside an article detailing a serious problem. They showed a 20 percent increase in problem-solving ability compared with participants who only read the article. Gielan says the results of the second study became part of the impetus to write Resilient Optimism.

At its heart, Resilient Optimism sets out three core truths: that resilient optimism can be developed, that it is intentional and that we can build an ecosystem of optimism around ourselves. This isn’t about forcing positive emotions or ignoring reality. It’s about building simple, repeatable behaviours that create a positive mindset and make it stick.

Gielan guides readers through a practical, science-based set of behaviors that can transform challenges into fuel for resilient optimism, performance, and well-being:

• Recalibrate your mindset: intentionally focus on what’s working, document the wins, and curate sources of optimism.
• Transform your stress response: reframe stress as a source of energy, clarity, and growth rather than only a threat.
• Triage your commitments: prioritize what creates the most meaningful impact and reduce low-impact obligations.
• Recharge more smartly: treat rest and time off as a performance strategy, not a reward after burnout.
• Connect the dots: create and notice small moments of meaning, momentum, and positive action to interrupt negativity and helplessness.

Resilient Optimism includes a wide range of case studies from workplaces and schools to hospitals and homes. Grace, a veteran ICU nurse, has a worn folder labelled “In Case of Emergency” in her hospital locker. Inside it are thank you letters and cards from patients and families who she has helped over the years. She opens the folder to read the curated memories of their gratitude, and this helps her to recalibrate when it’s especially stressful.

Jessica is a senior marketing strategist who has built her reputation as a go-to problem-solver. She knew it was time to stop saying yes to everything and taking on last-minute requests, but her concern that people might think she was slacking made it hard to change.

As Gielan explains, sometimes the hardest part of triaging commitments (chapter 4) isn’t the logistics, it’s the identity shift it demands. After this was reframed as making space for what mattered, Jessica was able to change. What’s more, it increased the respect people had for her.

It was also fascinating to understand that our brains are pattern-making machines. Gielan uses the image of a dot to show how we can feel disempowered when we accumulate negative dots we didn’t actively choose. This is because the brain then strings them together into a negative pattern. Her answer is that we can use our own intent to connect positive dots instead as well as create new ones. These conscious actions give the brain a new narrative. I tried joining my own positive dots and it not only worked, but I felt it also helped to set up a good start for the next day.

The Verdict

Resilient Optimism has a warmth, honesty and relatable style that kept me turning the pages. Gielan tells her stories in such a compelling style that I felt as if I was there in person. This helped me to recognise a small piece of myself in people whose lives look nothing like my own, and to apply this awareness to my own life challenges.

Each chapter is supported by research, and the book includes plenty of practical and easy to use tools and takeaways.

In summary:

• Resilient optimism is built on the belief that our actions can lead to positive outcomes
• Clarity and courage help us focus on what matters most
• It’s important to prioritise the roles and relationships that fuel lasting well-being and impact
• It’s a skill anyone can develop, through small, repeatable behaviours
• A life where we’re always busy but don’t see meaningful results or feel fulfilled teaches the brain that our actions don’t matter.

All in all, Resilient Optimism is a must-read which offers a roadmap for thriving in difficult times. It’s also a good book to share with someone who’s actively focusing on their own self-improvement journey or going through a tough patch.
