Undefined Heart Centre in Human Design for Business
Human Design Heart Centre | Abigail Rebecca
The heart centre, also called the ego centre or will centre in Human Design, is one of the most misunderstood parts of the bodygraph. It governs willpower, self-worth, material desires and the drive to prove oneself. Only around 35% of the population have this centre defined. That means approximately 65% of people have it open or undefined and if you’re one of them, what I’m about to share could completely shift the way you understand yourself and your business.
If your heart centre is open or undefined, you don’t have consistent access to the energy of willpower, drive or self-esteem. That doesn’t mean you’re broken. It means your relationship with these qualities is fluid, shaped by your environment and the people around you. You’ll feel them strongly at times, especially in the presence of someone with a defined heart centre. Then, when you’re alone, it can feel like that inner fire vanishes.
This blog will walk you through how this shows up in everyday life, why it can feel so confusing or frustrating, and how to work with your energy instead of against it. Especially if you're a woman in business, trying to grow, lead and be visible in a world that often values consistency above intuition.
How an Open or Undefined Heart Centre Affects You
When we talk about the open or undefined heart centre, we’re talking about a centre that doesn’t produce consistent energy. In practical terms, it means:
You don’t have consistent willpower.
Your sense of self-worth may fluctuate.
You might struggle to keep promises or commitments, especially if made too far in advance.
You can fall into the trap of trying to prove yourself, even when you don’t need to.
This can feel unsettling. One moment you might feel deeply confident, driven, motivated. The next, it’s like someone pulled the plug. You question yourself. You wonder if you’re flaky or unreliable. You feel that dip in worth and think, “What’s wrong with me?”
Nothing is wrong with you.
This is exactly how an open or undefined centre functions. You’re designed to experience variability in this area. That variability is your wisdom. You’re deeply intuitive when it comes to ego, will, and worth. You don’t have a fixed way of experiencing these things. You feel them through others, and that means you can become incredibly attuned to the subtle dynamics playing out in a room, in a conversation, or in a client interaction.
The Superpower of the Undefined Heart
I have an undefined heart centre myself. And interestingly, around 90% of my clients do too. That’s not a coincidence. My intuition around this energy allows me to serve them deeply, especially when they’re navigating visibility, value, pricing and confidence.
When you’re open in the heart centre, you’re amplifying what you pick up. If you’re with someone who has strong willpower and healthy self-esteem, you might feel on top of the world. But when you’re alone, that energy fades. This isn’t something to fix but learning when to say yes, when to say no, and when to rest will be crucial to your leadership.
Common Patterns of the Open Heart Centre
Here are a few themes I see consistently in women with undefined or open heart centres:
1. Overpromising and Underdelivering (to Yourself)
You may find it difficult to keep commitments made in advance. You want to be someone who always shows up, but your energy changes. Then you feel guilty for cancelling, rescheduling or needing space.
A strategy I use personally is not committing too far ahead unless it’s absolutely necessary. Instead, I create spaciousness in my calendar and let myself check in closer to the time.
2. Controlling Behaviour as a Worthiness Mechanism
If you’ve ever felt the need to control the outcome, control the schedule, or control how others perceive you, it might be rooted in this undefined centre. Control can feel like safety. But often, it’s masking a deeper fear of not being enough.
When you learn to let go of control in favour of alignment, something shifts. The tight grip eases. Opportunities flow in that are more aligned than anything you could have forced into place.
3. Visibility Struggles and Undervaluing Services
Low self-worth can lead to undercharging, hesitating to share your offers or holding back from being fully visible. You know you're good at what you do, but there’s a gap between your inner knowing and your outer confidence.
This is where the inner work becomes essential. You get to anchor into your own value, without waiting for external validation. That’s how you grow sustainably.
Integrity Without Proving Yourself
One of the most empowering realisations for me was understanding that I didn’t need to prove my integrity through promises I couldn’t keep. I could honour my design, create a business model that worked for me, and still lead with integrity.
That might look like:
Building in flexibility to your calendar.
Being transparent with your clients about how you work best.
Creating boundaries around commitments.
Allowing yourself to say, “Let me sit with that and I’ll get back to you,” instead of forcing a quick yes.
You don’t need to prove yourself through hustle, competition or over-delivery. You just need to own your energy and design your business around it.
Why Competition Doesn’t Serve You
If you have an open or undefined heart centre, you’re not designed to thrive in competitive spaces. That includes masterminds or programmes that are rooted in high-pressure, comparison-led dynamics.
Even if the marketing says “community over competition,” you’ll likely still feel the subtle undercurrent of competitiveness. And it can trigger a spiral. You might start doubting yourself, trying to prove your place, comparing your pricing or offer suite to others.
Here’s what I recommend instead:
Choose spaces that feel calm, spacious and energetically clean.
Work with mentors who understand Human Design and respect your energy.
Design your own benchmarks for success, rather than relying on comparison.
Anchoring Into Your Worth: A Practical Exercise
One of the most powerful tools I share with clients, especially those navigating visibility blocks or self-worth wobbles, is the accomplishments list.
This is how it works:
Start from childhood. Write down everything you’ve ever accomplished that made you proud. Awards, achievements, moments of praise, experiences that shaped you.
Include emotional milestones. Times you supported someone, overcame a challenge, or learned something profound.
Keep going until it feels complete. This is not a short list. Let it grow.
Read it back regularly. Let it remind you of your own value. Let it anchor you when the ego wobbles.
When you carry your accomplishments into your work, your clients will feel it—without you having to say a word.
Designing Your Business Around Your Open Heart Centre
Your business doesn't need to look like anyone else’s. In fact, if you try to model it on someone with a defined heart centre, you’ll likely burn out.
Here’s what I recommend if you’re navigating this aspect of your chart:
Simplify commitments. Don’t overbook or overpromise.
Price based on your value, not your fears. Remember that you’re not just charging for your time—you’re charging for your energy, wisdom and experience.
Create visibility on your terms. You don’t need to be “on” all the time. You get to show up in a way that feels authentic, sustainable and powerful.
You Are Already Enough
This is the message I want you to take away.
You don’t need to chase worth. You don’t need to prove it. Your open heart centre doesn’t make you weaker, it makes you wise. It makes you intuitive. It makes you sensitive to value, alignment and integrity.
When you start treating yourself as worthy, before the likes, before the clients, before the revenue, that’s when things begin to shift.
Final Thoughts
If you have an open or undefined heart centre, give yourself permission to design your business around your energy. Honour your fluctuations. Let go of the need to prove. Anchor into your own worth. And trust that by doing so, you’ll become even more magnetic to the right clients, opportunities and success.
I’d love to know how this lands for you. If you’re ready to explore your Human Design further and create success that honours your energy, reach out and book a 2 hour Human Design Reading with me.
And if you haven’t yet, I highly recommend taking time to write your own accomplishments list. A reminder that everything you need is already within you.
