1-Page Summary1-Page Book Summary of The Power of Mattering

From the moment we’re born, we reach out to secure our first relationships. Throughout our lives, this primal need evolves into a drive to feel seen, heard, valued, and needed. When we experience a sense of mattering—when we feel valued by others and aware of how we add value—we’re more motivated, resilient, and engaged. These qualities affect every aspect of our lives, from our personal relationships to how we perform at work.

But in The Power of Mattering (2025), Zach Mercurio argues that organizations face a deepening crisis: Workers report feeling more invisible, unheard, and insignificant than ever. He contends this “mattering deficit” drives the loneliness epidemic, disengagement crisis, and mental health problems plaguing today’s workplaces. He also says that organizations have misdiagnosed the problem: They’ve treated disengagement, loneliness, and turnover as...

The Power of Mattering Summary What Is Mattering, and Why Is It Important?

To understand why organizations struggle with persistent disengagement, loneliness, and turnover despite massive investments in solutions to these problems, you first need to understand what mattering is and how it functions psychologically. In this section, we’ll define mattering, explain the virtuous cycle that makes it so powerful, examine what happens when it’s absent, and look at evidence of the current mattering deficit.

What It Means to Matter

Mercurio defines mattering as the experience of feeling significant to the people around you. This experience arises from two interconnected components: the emotional experience of feeling valued by others and the knowledge that you add value to their lives. The need to matter isn’t a preference or a personality trait—it’s a basic survival instinct. From birth, we’re wired to grasp for connection because our survival depends on mattering enough to someone that they’ll keep us alive. As we grow up, this survival instinct evolves into a psychological need to feel seen, heard, valued, and needed by those around us.

Mercurio distinguishes mattering from two related, but distinct, concepts: belonging and inclusion....

The Power of Mattering Summary The Mattering Deficit

Mercurio presents evidence of a troubling paradox: Despite organizations’ unprecedented investment in addressing workplace problems, people report feeling more insignificant than ever. In 2022, Gallup reported that employee engagement had reached a decade low, with seven out of 10 workers emotionally uninvested in their work. This decline occurred despite the employee engagement industry growing into a billion-dollar sector. The data reveals the depth of the problem: Only 40% of employees strongly agree that someone at work cares about them as a person—meaning six out of 10 people spend a third of their waking lives feeling uncared for. Only 30% believe someone at work recognizes and invests in their potential.

The loneliness epidemic provides more evidence. Despite being more connected than ever—the average person sends 30-40 text messages daily—loneliness continues to rise. Americans’ time in meetings has tripled since 2021, yet people feel more isolated. Mercurio argues this reveals a misunderstanding: The quantity of interactions doesn’t reduce loneliness; the quality does. What reduces loneliness is feeling that you matter. This raises a question: If the problem...

The Power of Mattering Summary How to Create Mattering

Now that we understand what mattering is and why organizations struggle with it, we can explore Mercurio’s framework for creating it in everyday interactions. His method consists of three practices: Noticing (making people feel seen and heard), Affirming (showing people how their unique gifts have an impact), and Needing (demonstrating that people are indispensable). These practices are learnable skills, not personality traits, that transform ordinary interactions into what Mercurio calls “moments of mattering.”

Noticing

Mercurio defines noticing as ensuring that people feel truly seen and heard, which requires that we deliberately counteract how our biases, time pressures, and attention deficits prevent us from accurately perceiving others. He emphasizes an important distinction: You can know someone without noticing them. You might know that your colleague has two kids, but fail to notice she’s been stressed for weeks because her childcare fell through.

Three barriers prevent effective noticing. First, the perceptual barrier: How you see people determines how you treat them, which influences who they become. We form quick judgments, then label people—seeing...

Shortform Exercise: Plan a Moment of Mattering

Mercurio argues that mattering happens in moments, not programs—and your next opportunity to create one for somebody is in your next interaction. This exercise will help you plan and execute one specific moment of mattering.

Think about someone at work who you believe might not feel fully seen, heard, or valued. Who are they, and what makes you think they might be experiencing anti-mattering?
