The Golden Circle, Human Brain and the 6 Human Needs
Have you ever found yourself binge-watching a show you don’t even like, eating a whole bag of chips when you’re not hungry, or agreeing to something you secretly didn’t want to do? Why do we do the things we do? The answer lies in a fascinating mix of psychology, neuroscience, and a little something called The Golden Circle. Buckle up—this is going to be a wild ride through the human mind.

The Golden Circle: Start With Why
Simon Sinek’s Golden Circle theory tells us that every action starts with a why. At the core of our decisions is a deep-seated purpose, surrounded by how and what. For example:
- Why: I want to feel connected to others.
- How: I’ll scroll through social media.
- What: I’ll like 50 posts in 10 minutes.
This golden circle is based on how our brain works and how we can drive emotions through our value proposition: if we start with the Why, we are communicating our motivation, our beliefs; with the How, the actions we will have to take to fulfill the Why, and finally, the What, the resulting artefact.
It seems so easy that it seems obvious, but you would be surprised how many people or organisations do not think about the Why of their actions.
In other words, the Why and the How communicate with our limbic system, influencing the behavior and decision making of our listeners; while the What, the neocortex, focuses on the rational part, not being so critical for our listeners, being the why of our design process, where the why is more critical than the final artefact itself.
But here’s the kicker: our why isn’t always conscious. Sometimes, it’s driven by primal needs wired into our brains. Which brings us to…
The Human Brain: A Drama Queen in a Lab Coat
Our brain is like a over-caffeinated scientist, constantly running experiments to keep us alive and (relatively) sane. The limbic system, the emotional part of our brain, often hijacks the logical prefrontal cortex. This is why you might cry during a dog food commercial or eat an entire pizza after a bad day.
Fun fact: Your brain releases dopamine (the “feel-good” chemical) not when you achieve a goal, but when you anticipate it. This is why scrolling through Netflix for 45 minutes feels better than actually watching the movie.
The Six Human Needs: What Drives Us
What shapes human behavior? Why is there violence, greed and negativity in the world? Is it human nature or can it be stopped? Great minds have been debating these essential questions for centuries.
You don’t have to be a philosopher to want to understand human behavior. It’s just as important for your personal growth. Because by understanding the needs that shape your behavior, you will be able to take back control over your life and learn how to create new patterns that lead to lasting fulfillment. Once you’re able to identify which human needs have been driving your decision-making, you can more accurately work to fulfill those needs.
You can also predict others’ needs and better respond to them. Whatever emotion you’re after, whatever goal you pursue – whether it’s building a business, understanding your partner, raising a family or traveling the world – the Six Human Needs are a powerful tool.
According to Tony Robbins, all human behavior is driven by six core needs. These needs explain why we do the things we do, even when they don’t make sense:
1. Certainty: We crave stability and predictability. (Hello, routines and comfort zones!)
2. Uncertainty/Variety: But we also need excitement and novelty. (Hence, why we binge-watch thrillers.)
3. Significance: We want to feel important and unique. (Posting that selfie, anyone?)
4. Connection/Love: We’re wired to bond with others. (Even introverts need their people.)
5. Growth: We need to feel like we’re improving. (Cue the New Year’s resolutions.)
6. Contribution: We want to make a difference. (Volunteering, mentoring, or even just sharing this blog post.)
These needs are like a psychological cocktail, and we’re all mixing them differently. For example, someone might crave certainty by sticking to a 9-to-5 job but satisfy their need for variety by skydiving on weekends.
The Power of Certainty: Your Brain’s Security Blanket
There is one need that is the most common answer to why we do what we do: certainty. We all need to feel certain that we can avoid pain and that, ideally, we can have comfort. The need for certainty is a survival need. As Tony says, “People are driven by more than one thing. And often that thing is certainty.”

Other needs are more spiritual. Tony says, “Everyone finds a way to fulfill the other needs, but very few find a way to fulfill these needs.” Will you be one of the few? Listen to the podcast to hear which needs are most powerful, which are spiritual and how you can fulfill them all in healthy ways.
Once you understand the Six Human Needs, “You will never see the world the same way if you stay awake. Instead of seeing people’s behaviors, you’re going to see their attempts to meet their needs.”
Certainty is the MVP of human needs. Our brains love predictability because it reduces stress and conserves energy. This is why habits—good or bad—are so hard to break. Your brain thinks, “Hey, this worked before, let’s do it again!”
Fun tip: If you want to build a new habit, start small and make it predictable. For example, if you want to exercise more, commit to just 5 minutes a day at the same time. Your brain will latch onto the routine, and soon you’ll be doing it without thinking.
But here’s the twist: too much certainty can make life feel stale. That’s why we need a dash of uncertainty to keep things interesting. It’s like adding hot sauce to your tacos—just enough to keep you on your toes.
Fun Facts to Blow Your Mind
- The average person makes 35,000 decisions a day. No wonder we’re tired!
- Your brain uses 20% of your body’s energy but only makes up 2% of your weight. Talk about high maintenance.
- The phrase “comfort zone” was first used in 1908 to describe a temperature range. Now it’s a psychological metaphor. Cozy, right?
The Existential Twist
So, why do we do the things we do? Is it all just a mix of brain chemistry, psychological needs, and a quest for certainty? Or is there something deeper—a cosmic why that drives us beyond survival and satisfaction?

Here’s the existential question to ponder: If our brains are wired to seek certainty in an uncertain world, are we truly free to choose, or are we just following a script written by evolution?
Think about it. Or don’t. Either way, your brain will probably reward you with a little dopamine hit for considering it.
What’s your why? Share your thoughts in the comments—or just go eat some chips. No judgment here ;)
If you're curious ans still want to discuss some behaviors or repetitive patterns you have, understand the Why, How and What, feel free to book a session here with a therapist in Hong Kong.
