„Taming the Molecule of More” Book Review

Michael E. Long | BenBella Books, 2025. One of the most compelling practical psychology books of 2025, Taming the Molecule of More taps into a question many of us quietly struggle with today: why, despite having more than ever before, do we still constantly want more? Why does achievement so quickly turn into emptiness? And why does the phone pull us in like a magnet even when we know there is nothing truly important waiting there?

This book does not just explore these questions – it offers tools to work with them. Michael E. Long, a writer with a background in physics, playwrighting, and language studies, and a lecturer at Georgetown University, previously co-authored the international bestseller The Molecule of More with psychiatrist Daniel Z. Lieberman. That book, translated into more than 20 languages, reshaped how millions of readers understand desire, motivation, and relationships.

This new book is a long-awaited continuation. If the first book explained what dopamine is, this one focuses on what to do with that knowledge.

Dopamine is often referred to as the “molecule of more” – the neurochemical that drives us toward novelty: a better job, a newer phone, a more ideal relationship. It constantly promises satisfaction whenever we encounter something new and enticing. The problem is that it only promises it. The actual experience of contentment is produced by other systems in the brain, while dopamine has already moved on to the next target.

This is not a weakness of character – it is biology. And this is where Long’s argument begins: once you understand the mechanism, you can start to work with it.

The book is structured into four parts. The first offers a concise but solid overview of dopamine science, accessible even to those unfamiliar with the original book. Long explains two key dopamine systems: the desire system, which drives us forward, and the control system, which helps us pause and choose. A balanced life requires both.

The second part is the most scientific – and arguably the most fascinating. Long explores how dopamine interacts with modern life: social media, gaming, romantic relationships, and work. Instead of abstract theory, he focuses on concrete mechanisms: why “likes” function like slot machines, why the excitement of new love fades after a few months, and why workaholism is often not discipline, but a dopamine loop.

The third and fourth parts form the practical core of the book. Long offers step-by-step approaches across several areas:

Social media and technology. Not about quitting, but about understanding the mechanism and learning to interrupt automatic responses. He provides practical techniques for reshaping our relationship with the phone.

Relationships and romance. One of the strongest sections of the book. Long explains why the excitement of a new partner inevitably fades – and why this is not the end of love, but simply dopamine biology. More importantly, he shows that desire in long-term relationships can be revived, even after many years.

Creativity and motivation. How to enter a creative state when needed, rather than waiting for inspiration. Long connects dopamine with divergent thinking and shows how to intentionally create conditions for creativity to emerge.

Compulsive habits. From endless news scrolling to online shopping, he breaks down the mechanisms that keep us stuck in loops and offers practical steps to break them.

What stands out most is that Long avoids generic advice or vague calls to “be present.” He does not ask readers to meditate for an hour a day or radically detach from modern life. Instead, his approach is grounded in science and everyday situations people can easily recognize in themselves.

Importantly, he does not moralize. Dopamine is not framed as an enemy. On the contrary – the book shows how this powerful neurochemical can become an ally once we learn how it works.
