What makes people often decide whether to trust or respect someone within the first few seconds?
People decide within the first few seconds because human perception is deeply rooted in instinctive survival mechanisms that evolved long before humans learned to speak.
Nonverbal communication came first. Living beings survive by reading signals from posture, movement, facial expressions, eye contact, physical tension, and energy. These signals communicated danger, safety, dominance, fear, aggression, openness, or connection.
That system never disappeared. We simply added speech on top of it. But the reptilian brain, the oldest part of the brain responsible for survival and instinctive reactions, still responds first. Before the conscious mind and the neocortex begin logical analysis, the subconscious has already started evaluating the person in front of us.
This process happens automatically and extremely fast. The brain constantly scans for signals of emotional stability, confidence, authenticity, stress, insecurity, or potential threat. That is why people often feel a sense of trust or discomfort before they can logically explain why.
Words are important, but they are processed later. The first language humans still instinctively respond to is body language. And in leadership, negotiations, business, and everyday interactions, those silent signals often shape perception long before logic fully enters the conversation.
Was there a moment in your career when you realized body language influences success more than most people understand?
Yes. It actually started during my corporate career, long before I became a body language expert. I worked my way up from project manager to director of projects and later to CEO, so for many years I was deeply involved in leadership, sales, team management, and training. And that’s where I began noticing something very interesting.
I observed that some sales professionals knew the product inside and out, delivered strong presentations, used the right words, and followed the same sales process as everyone else, yet their results were completely different. Some built trust with clients almost instantly. Clients felt comfortable with them, felt listened to, agreed with them, and wanted to continue communicating. Others said almost the same things, but struggled to create that same connection.
That made me curious. I started observing people more closely and analyzing exactly what created this difference in perception. And I realized that people were not reacting only to words or expertise. They were reacting to behavior, emotional signals, presence, energy, and nonverbal communication.
Many people call this “charisma,” but the more I researched human behavior, the more I understood that charisma is not some magical inborn trait. Very often, it is a combination of nonverbal signals that create trust, emotional connection, credibility, rapport, and a feeling of psychological comfort around a person.
That realization completely changed the way I looked at communication, influence, leadership, and professional success.
Many professionals work hard on their skills and knowledge. Why do some still struggle to be truly noticed?
I remember my late father telling me something when I was around fifteen that stayed with me for life. He said, “People first notice how you present yourself. And that determines whether they even want to learn more about your expertise or abilities.”
At that age, I believed that being smart, talented, hardworking, and competent should be enough. But later, through life and business experience, I realized reality works differently.
People often respond first to presence, confidence, energy, and the way someone carries themselves. Only after that do they become interested in the person’s actual expertise.
I’ve seen highly capable professionals remain unnoticed simply because they failed to create that initial connection. At the same time, others opened doors more easily because their presence made people feel comfortable, engaged, and willing to listen further.
In many ways, nonverbal communication works like a first-level casting process. Before people decide whether they trust your knowledge or expertise, they subconsciously decide whether they are emotionally open to you. That first impression becomes the gate. And if the gate doesn’t open, people may never fully discover what you are truly capable of.
What inspired you to write your book, Win Before You Speak, at this stage of your career?
I think this book became a natural result of 20 years of observing people, business communication, negotiations, leadership, and human behavior. Throughout my career, I repeatedly noticed that highly intelligent and capable professionals often failed to achieve the results they deserved, not because they lacked knowledge or expertise, but because their nonverbal communication was working against them.
Strong negotiations collapsed because trust and rapport were never fully established. Excellent sales presentations failed to create a connection. Qualified professionals lost opportunities during interviews, presentations, or even exams because stress, tension, or insecurity became visible through their body language before they could fully express themselves verbally.
What fascinated me was realizing how strongly people are judged not only by what they know, but by how confident, trustworthy, emotionally stable, and convincing they appear in the moment. The brain processes signals first and words second. Before logic fully analyzes information, people already react subconsciously to posture, eye contact, facial expressions, movement, and emotional control.
I also realized that nonverbal communication is not some mysterious inborn talent. These behaviors can absolutely be trained and consciously adapted depending on the situation and the result a person wants to achieve.
That is why I wrote Win Before You Speak not simply as a theoretical book, but as a practical playbook. It includes more than 100 exercises, techniques, and practical tools designed to help people consciously manage the impression they create, strengthen trust, improve influence, read others more effectively, and develop mastery of their nonverbal presence in business, negotiations, leadership, interviews, presentations, and everyday communication.
What’s one nonverbal habit that instantly changes the way a person is perceived in business settings?
One of the strongest nonverbal habits that instantly changes how a person is perceived in business settings is remaining physically calm under pressure.
The moment people become stressed, uncomfortable, or insecure, the body usually reacts automatically. Speech speeds up, movements become chaotic, eye contact changes, facial tension appears, posture collapses, or the person starts making restless gestures without realizing it. Even if their words sound confident, the body often communicates the opposite.
What’s interesting is that people around them usually feel this emotionally before they consciously analyze it. The brain naturally associates calmness, grounded movement, controlled pace, and emotional stability with competence, confidence, leadership, and trustworthiness.
I often say that calmness is not passiveness. Calmness is controlled power. A person who can stay physically composed under pressure communicates certainty and self-control without needing to prove it verbally. And in business environments, that changes perception immediately.
If readers take away only one message from your book, what do you hope it will be?
I hope it is the understanding that nonverbal communication should never be ignored, because it influences opportunities, trust, perception, and outcomes far more than most people realize.
What’s interesting is that many world leaders, top negotiators, high-level executives, diplomats, politicians, and elite sales professionals already understand this, even if they don’t always consciously explain it.
Over years of experience, observation, negotiations, and leadership, they learn how strongly human behavior, emotional control, presence, and nonverbal signals shape communication and influence results.
The problem is that most people are never formally taught these skills. They spend years learning through trial and error, often losing opportunities without fully understanding why certain negotiations failed, why trust was not established, why they were overlooked, or why someone else with less expertise achieved stronger results.
So, I wanted to create a practical shortcut, an accelerated way for people to understand the nonverbal dynamics that usually take decades of real-life experience to recognize and master.
The book is not only about learning how to present yourself more effectively. It is also about learning how to understand other people through their nonverbal signals. Communication is always two-sided. The body often reveals emotions, hesitation, discomfort, agreement, resistance, confidence, or uncertainty before words are spoken.
For example, in sales, people trained to recognize nonverbal behavior can often detect objections before the client verbalizes them. In negotiations, experienced professionals learn to “read the room”, to sense tension, emotional shifts, openness, resistance, power dynamics, or changes in energy before the conversation openly changes direction.
This ability becomes incredibly powerful because it allows people to anticipate reactions, adapt communication in real time, prevent unnecessary conflict, build stronger rapport, and navigate conversations with much greater awareness and control.
Ultimately, the book's core message is simple: communication begins before words, and people who understand both how to manage their own nonverbal communication and how to read others' nonverbal cues have a significant advantage in business, leadership, negotiation, and human interaction.
