This center has several names - the Heart, Ego, and Will Center, and I refer to this center as the Ego Heart Center. To be clear though, the heart, soul, and higher self are located in the G Center. So why is it called the Ego Heart Center? The confusion comes from the dual nature of the word "heart." In one definition, the heart is connected to love, soul purpose, and higher consciousness—which aligns more with the G Center in Human Design. In another definition, the Ego Heart Center represents the biological heart, willpower, and the drive to achieve in the material world.
The Ego Heart Center governs our sense of value, our ability to commit, and our relationship with personal power, which is very different from the soul-level identity of the G Center.
63% of the population have an undefined or open Ego Heart Center.
If you have an undefined or open Ego Heart Center, understand ingwhat this center is about and being able to differentiate between the Ego Heart's high expression and the Ego Heart's conditioning can be life altering!

Energetic Themes of the Ego Heart Center
The Ego Heart Center is a powerful motor and it's about "I, me, mine." The energy is the source of our willpower, motivation, ego, generating and managing physical resources, and the material world. These are very influential forces in the world.
The material world is defined as anything that’s physical or supports our physical needs, including money, time, property, homes, food, supplies, your physical body.
Undefined Ego Heart Center Conditioning
An Undefined or Open Center does not have consistent and reliable energy output. Instead, it is where you take energy in from others, and that often feels like amplified energy in your body. Being able to "feel" another person in this way can make you very wise about the theme of the Ego Heart Center, which is a great thing!
Where you can run into problems is when you identify with what you experience through your undefined center as your true self. The undefined centers are prone to conditioning.
High Expression of the Undefined and Ego Heart Center
With an undefined Ego Heart Center you are capable of having a wise perspective about inherent value and self-worth. You trust you have inherent worth. You can discern which way of seeing your own value and worth is healthy for you. You accept you have nothing to prove. You rely on your Strategy and Authority to provide for your needs.
This undefined Ego Heart Center is also how you experience others, and you can tell if what you’re receiving is healthy for you. You especially have a wise sense about trustworthiness of another person's word, and the use of money and personal power on the material plane.
With an undefined Ego Heart you can feel when you're motivated and when you aren’t, and when in alignment, you are able to let go of needing to feel motivated all the time. You learn to trust that you have the exact amount of motivation you need and honor that.
You use your Authority to determine which promises or commitments you have energy for, and most importantly, which commitments are correctly aligned for you. And…if you enter into a commitment incorrectly, you don’t force yourself to keep it and don't feel unworthy about backing out.
Worth and Value in an Undefined Ego Heart Center
Self-worth and self-value stretches into every aspect of life, so this is the center prone to the most conditioning in life. Be honest with yourself. Where are you valuing and undervaluing yourself or putting pressure on yourself?
Don’t beat yourself up if you don’t have the energy to work on something. Just say, “I’m not meant to work on it today." Allow yourself to rest.
Low Expression of an Undefined Ego Heart Center: Doing thigs to prove yourself, lacking self worth, and underestimating your value.
Willpower and Motivation in an Undefined Ego Heart Center
There's a lot of conditioning in our society to always be motivated, to always be connected to something, and to have willpower toward goals and everything you want to accomplish in life.
As said above, notice when you’re motivated and when you aren’t, and let go of needing to feel motivated all the time.
An undefined Ego Heart Center is susceptible to taking in and amplifying the willpower and motivation of someone who has a defined Ego Heart Center. This can feel deceiving because it can feel like you suddenly have the will to make and keep a commitment. This "borrowed" willpower evaporates, however, as soon as the person with the defined Ego Heart Center leaves.
When you have no motivation, lay on the couch and do a meditation, feeling into your inherent worth as a human being on Earth. This is a muscle you can build and practice.
5 Tips to Reach Your Nutrition and Exercise Goals with an Undefined Ego Heart Center
I've been a Registered Dietitian for 24 years, and have worked with thousands of clients to improve their health, reach their health goals, make lifestyle changes, and connect with their body through intuitive eating. It takes time, and one thing I've learned? Motivation ebbs and flows—especially for those with an undefined Ego Heart Center.
1. Ditch the "All or Nothing" Mindset
People with an undefined Ego Heart often set big, ambitious goals, only to struggle with follow-through. Instead of forcing motivation, focus on small, sustainable actions that feel good in the moment rather than relying on sheer willpower.
💡Example: Instead of committing to a strict workout plan, choose intuitive movement. Ask yourself, "What does my body need today?"
2. Stop Trying to Prove Yourself Through Diet & Exercise
With an undefined Ego Heart, you might feel pressure to prove your worth through achievements—whether it’s hitting a certain weight, following a "perfect" diet, or pushing through workouts even when exhausted.
✨Reframe it: Health is about how you feel, not about proving something to yourself or others. Choose foods and movement that nourish and energize you, not ones driven by external expectations.
3. Work with Your Energy, Not Against It
Unlike those with a defined Ego Heart, you don’t have a consistent energy reserve for pushing through goals. Instead of relying on motivation, build routines that flow with your natural energy cycles.
💡Try this: Schedule flexible workouts that allow for high-energy days and rest days instead of forcing a rigid plan.
4. Set Gentle Goals with Room for Flexibility
Instead of "I will work out every day at 6 AM," try "I will move my body in ways that feel good 4–5 days a week." This approach removes the pressure to force motivation and allows you to tune in to your body's needs.
5. Surround Yourself with the Right Support
An undefined Ego Heart absorbs the motivation and willpower of others, so who you surround yourself with matters. Seek accountability partners, coaches, or communities that inspire you without pressuring you to prove your worth.
💡Tip: If you work better with gentle external motivation, try group classes, workout buddies, or an intuitive eating coach to keep you connected without overcommitting.
The Undefined Will vs the Mind
With an Undefined or Open Ego Heart Center, the mind can easily take over. If you notice your mind having thoughts related to trying to prove your worth or value in any way, pause, and "put them in check." This is a time to shift your self-talk into, "I have NOTHING to prove" and truly feeling you are inherently worthy no matter what!
I want to provide some examples of what it might feel or sound like if the mind takes over and the Ego Heart Center slips into a low expression - this is typically caused by conditioning, and noticing this talk is essential to deconditioning.
I better do this because if I don't, I won't be worthy.
Trying to prove you’re good enough or trying to prove you're a good person.
Trying to prove yourself with material achievements (ie: money, time).
I have to be in control. I have to be brave.
I have to be loyal so others will see how valuable I am, and so I can prove to myself how valuable I am.
Trying to prove your value.
Trying to prove you can deliver on your promises even if it leads to burnout.

Human Design Appointments
Moving from where you are now to where you want to be requires long-term dedication to learning and experimenting with your human design. I've learned so much through the process of researching, observing myself and others, experimenting, and repeating that cycle over and over.
I believe real growth takes more than one appointment, which is why I offer an initial appointment (90 minutes) with a follow-up appointment (60 minutes).
If you think a one time appointment is more ideal for you, I also offer that option.
