Amazing!!!đ
I once spent forty-five minutes deciding which brand of peanut butter to buy. Not exaggerating. Natural vs. regular? Crunchy vs. smooth? What about the sugar content? The environmental impact of the palm oil? Did I deserve the expensive one? Would the cheap one make me feel like a failure? I stood in that aisle, phone in hand, reading labels and reviews, while my partner texted from home: "Did you get kidnapped by the peanut butter?"
That is overthinking. And if you know, you know.
Joseph Nguyen's The Overthinker's Guide to Making Decisions is a slim, punchy book written for people like me, people who can turn a simple choice into a philosophical crisis, who run every decision through a mental simulation of every possible outcome, who exhaust themselves before they have even done anything. Nguyen is the author of the bestselling Don't Believe Everything You Think, and this book continues his signature style: short chapters, bolded takeaways, and a direct, almost blunt writing style that feels like a friend shaking you gently by the shoulders.
What I appreciated most is that Nguyen does not pathologize overthinking. He does not tell you that you are broken or anxious or neurotic (though you might be, and that is fine). Instead, he reframes overthinking as a well-intentioned but deeply inefficient strategy. Your brain is trying to keep you safe by analyzing every variable. The problem is that the world is too complex to be analyzed into certainty. You will never have all the information. You will never eliminate all risk. And waiting for certainty is just waiting to stay stuck.
The book is structured around a few core principles and then applied to different domains of decision-making: career, relationships, money, daily choices, and major life transitions. Each chapter ends with a "Decision-Making Shortcut"âa simple rule or question that cuts through the noise. For example: Would I regret this more if I did it, or if I didn't? Or: What would I tell my best friend to do?
The book is not groundbreaking in the sense of offering entirely new ideas. You have probably encountered some of these concepts before, the 5-Second Rule, the 80/20 principle, the concept of "satisficing" over "maximizing." But Nguyen's gift is synthesis and delivery. He takes ideas from psychology, productivity, and philosophy and boils them down into actionable, bite-sized chunks that you can actually remember when you are standing in the peanut butter aisle.
5 Lessons:
1. Overthinking is not the same as thinking carefully.
Nguyen draws a crucial distinction early on: careful thinking is intentional, time-bound, and directed toward action. Overthinking is repetitive, circular, and designed to delay action. If you are gathering information, weighing options, and then making a choice, that is careful thinking. If you are replaying the same variables, imagining disaster scenarios, and still not deciding, that is overthinking. The first is useful. The second is a trap. The goal is not to stop thinking. It is to stop thinking in circles.
2. Most decisions are reversible. Act like it.
One of the biggest drivers of overthinking is the belief that the decision you are making is permanent and life-altering. Nguyen challenges this directly. Unless you are choosing a spouse, having a child, or jumping out of a plane without a parachute, most decisions can be undone. You can switch jobs. You can move back. You can apologize. You can change your mind. The fear of making the "wrong" choice keeps you stuck, but the truth is that few choices are truly one-way doors. Ask yourself: If I make this choice and it turns out badly, can I undo it? If the answer is yes, stop overthinking and decide.
3. Perfection is the enemy of done.
Nguyen quotes Voltaire (or maybe he quotes someone quoting Voltaire): "Perfect is the enemy of good." Overthinkers are often perfectionists in disguise. You are not trying to make a good decision; you are trying to make the best possible decision, which is a moving target that does not exist. The solution is to aim for "good enough"âwhat psychologist Herbert Simon called satisficing. A good enough decision made today is infinitely better than the perfect decision made never. Choose good. Choose done. Choose moving on with your life.
4. Your feelings are not data.
This was the lesson that hit me hardest. Overthinkers often treat their anxiety as evidence. I feel nervous about this decision, so it must be risky. I feel uncertain, so I must need more information. Nguyen argues that anxiety is not a sign that you are making the wrong choice. Anxiety is a sign that you are making *a* choice, and your brain, which prefers the devil it knows, is throwing a tantrum about the uncertainty. The solution is not to wait until you feel calm. The solution is to decide anyway, and let your feelings catch up later. Feelings follow actions far more often than they precede them.
5. The cost of not deciding is higher than the cost of deciding wrong.
Overthinkers are exquisitely sensitive to the potential downside of their choices. What if I pick the wrong restaurant and everyone is disappointed? What if I take the job and hate it? What if I say the wrong thing and they never speak to me again? But Nguyen asks you to consider the flip side: what is the cost of not deciding? The lost time. The lost opportunity. The slow erosion of your confidence as you realize you cannot trust yourself to act. In most cases, the cost of indecision is higher than the cost of a wrong decision. A wrong decision gives you information. Indecision gives you nothing but a stuck life.
The Overthinker's Guide to Making Decisions is not a book for people who want to understand the psychology of rumination. It is a book for people who are tired of standing in the peanut butter aisle. Who are exhausted by their own mental committee. Who have missed opportunities not because they chose poorly, but because they could not choose at all.
Joseph Nguyen has written a short, practical, compassionately blunt guide for the indecisive. He will not hold your hand through every decision. He will not promise that you will never make a mistake. What he will do is give you permission to decide, imperfectly, anxiously, without all the information, and trust that you can handle whatever comes next.
Because you can. You have before. And the only way to prove it to yourself is to finally, finally choose.
