Why ADHD Struggles Are Often System Problems, Not Personal Failures – Interview with Kim van Dijk

Kim van Dijk is the founder of MindCastle Creations, an ADHD Systems Expert, entrepreneur, and author of It's Not You, It's Your System. Drawing from her own experience with ADHD, burnout, and entrepreneurship, she has developed a practical approach that helps neurodivergent people replace self-blame with systems that work with their brains. In this interview, she shares the personal journey behind her philosophy, why traditional productivity advice often falls short, and how changing your systems can change your life.

Kim van Dijk, Founder of MindCastle & ADHD Systems Expert

Looking back, what experiences led you to realise that the biggest challenge was not your ADHD, but the systems you were expected to fit into?

I started strong, and then stopped the moment I fell behind. Missing a few days turned the planner into a guilt object. Starting over became a pattern, and shame followed every attempt. I knew I was capable. I knew I was smart, but my systems kept assuming I would be consistent, linear, and energized, and my brain simply isn't.

The turning point wasn't a dramatic moment. It was realizing the same loop kept repeating, I'd get motivated, make a “perfect” plan, life would happen, I'd fall behind, and I'd decide the problem was me. That's when it clicked, this wasn't a motivation issue. It was a system issue.

Around the same time, I started watching my child struggle with many of the same things I had, including overwhelm, forgetfulness, and falling behind in systems that weren't built for an ADHD brain. Seeing it through their eyes made something very clear to me, this wasn't a personal failure. It was a design failure.

I didn't want the next generation growing up believing their brain was the problem too. That's when this stopped being just about me and became about creating something that actually supports ADHD brains, gently and practically, from the start.

Your book is called It's Not You, It's Your System. What inspired that message, and why did you feel it was important to challenge the way people think about ADHD?

The title came from something I kept hearing and kept telling myself, “If I just tried harder. If I was more disciplined. If I wasn't so scattered.” The implication was always the same, I was the problem. I was exhausted from believing it.

I realized I'd spent years trying to run Windows software on a Mac and then blaming myself when it didn't work. I wasn't broken. The systems I was using were designed for a different operating system entirely.

So the book exists to challenge that narrative. Not because ADHD isn't real, it absolutely is, and it's neurobiological, but because most of the shame and struggle comes from using tools that were never designed for how ADHD brains actually work.

Planners that assume you'll check them daily without reminders. Productivity advice that treats motivation like an on/off switch. Systems built for linear, consistent energy, when ADHD brains are anything but.

What I wanted people to understand is this, your brain isn't the problem. The systems are. Once you stop blaming yourself for things that are wiring, not character flaws, everything shifts. You can start building a life that actually fits your brain instead of spending all your energy fighting it.

You can learn your operating system's features, not just the bugs everyone points out. That's the permission this book gives you. I felt it was important because too many people are drowning in shame when what they actually need are different tools.

How did that idea grow from a personal realization into MindCastle Creations and the work you do today?

At first, I honestly thought I was creating a planner. I had already built a web design agency, so I understood business and scalability, but I was thinking about passive income, something that didn't require the same one-on-one time investment that client work demanded.

That's when MindCastle started as an idea. The real catalyst came from my son. He suggested the planner concept, something designed specifically for ADHD brains, not a generic productivity tool.

We built it, listed it on Amazon, and it took off. That success showed me something crucial, there was real demand for tools designed for ADHD people, not at them.

Once the planner started working, I looked at everything else I'd already created for myself and my family, including the systems, templates, and tools that had changed how we lived. I thought, "Why keep these to ourselves?" I already had them. They worked. So I started selling them too.

The brand grew because the tools actually solved real problems. People weren't just buying a planner, they were buying something that finally worked with their brain instead of against it.

Here's what I noticed, having the right tools wasn't enough. People needed support. They needed to understand why these systems work. They needed accountability, community, and someone who understood the ADHD experience guiding them through implementation.

That's when MindCastle Creations became what it is today, not just selling tools, but building a complete ecosystem where people can learn the philosophy, get the practical systems, and actually implement them with real support.

The eight-week program exists because people asked for the next level, “How do I actually build this into my life?” MindCastle isn't about selling more stuff. It's about creating a castle people can actually live in, not just buy a blueprint for.

Why do you believe so many people mistake struggling with poorly designed systems for a lack of motivation or discipline?

ADHD masking is invisible. People see someone who appears functional, who shows up, and who gets things done, but they don't see the elaborate systems running in the background. They don't see the extra energy being spent just to appear normal.

So when someone with ADHD struggles, the blame lands in the wrong place. It's not “this system doesn't work for their brain.” It's “they're lazy,” “they lack discipline,” or “they're not trying hard enough.”

Here's the brutal part, people start believing it about themselves. You buy another planner. You download another app. You promise yourself this Monday will be different. You create elaborate systems that would make a project manager weep. Then you can't stick with them, which just confirms the lie you already believed, something is wrong with me.

Here's the truth, your brain isn't broken. It's wired for improvisation, not factory settings. You handle crisis incredibly well and routine incredibly badly. You need external structure where other people rely on internal habits. That is not a personality defect. It is a design mismatch.

Most people don't understand this distinction. They think willpower is the problem, so they blame themselves. They try harder, buy more planners, download more apps, and the cycle continues.

What they actually need is different design, a system that works with their brain instead of against it. Once you realize that, everything shifts. You stop trying to fix yourself and start building systems that fit.

Traditional productivity advice often encourages people to change themselves. What do you think becomes possible when they start changing their systems instead?

Everything. Seriously. When you stop trying to become someone else and start designing for who you actually are, the relief alone is transformative.

Traditional productivity advice is built on a lie, that if you're disciplined enough, motivated enough, or committed enough, you can do anything. So you internalize the message that your failures are personal failures. You're not organized enough. You're not focused enough. You're not trying enough.

Here's what actually happens when you shift to systems, you stop wasting energy on self-improvement and start building things that work.

Instead of “I need to be more disciplined,” it becomes “I need a system that works without relying on discipline.” Instead of “I should be able to focus on boring tasks,” it becomes “Let me design tasks in a way that doesn't require my brain to generate dopamine for something it can't.” Instead of “I'm lazy,” it becomes “I need external structure and accountability, and that's just how I function best.”

When you make that shift, suddenly you're not fighting yourself anymore. You're not burning energy trying to be someone you're not. You can actually live instead of constantly trying to fix yourself.

Here's the beautiful part, systems scale. A system that works for you can work for your family, your team, and your business. You're not building a life around willpower, you're building a life around design.

That's sustainable. That's actually possible.

Most people spend their entire lives trying to be different. What becomes possible when you finally stop?

Your philosophy has evolved into a book, practical tools, and educational programmes. How do those different pieces help people turn ADHD knowledge into systems they can actually use?

Knowledge alone doesn't change lives. I learned that quickly.

You can understand intellectually that “your brain works differently” and still feel like a failure when you can't stick to a system. You can know that ADHD isn't a character flaw and still spiral into shame when you forget something important.

Understanding and doing are two completely different things.

That's why the different pieces exist. They're designed to work together.

The book gives you the why. It's grounded in real examples from my experience, but it's really about your systems and how to build them. It helps you stop blaming yourself for things that are wiring, not character flaws. It shows you that you're not broken, the systems are, but knowing that intellectually isn't enough. That's where the tools come in.

The planner and the workbooks are designed to get you out of your head and into something practical. They're not generic productivity tools. They're built around how ADHD brains actually function, with external structure, flexibility for chaos days, and permission to not be linear.

Here's the thing, even the right tools don't work if you're using them alone. That's why the eight-week program exists. It takes the workbook, the backbone of everything, and adds the layer that actually changes behavior, accountability, community, and someone who understands ADHD guiding you through implementation.

Less fixing. More understanding. Less forcing. More building.

That's not just a tagline, it's the architecture of how everything works together.

The book rewires how you think about yourself. The tools give you something practical to do. The program gives you the support to actually stick with it and build a life that fits your brain.

For someone who has spent years blaming themselves for struggling, what is one practical change that can make everyday life feel more manageable?

Stop separating “I failed” from “this setup doesn't fit how my brain works.” That sounds simple, but it's everything because most of the shame people carry isn't actually theirs to carry.

School was designed for kids who self-regulate easily and thrive on routine. Work assumes you'll self-motivate on boring tasks without external structure. Your planner assumes you'll check it daily without reminders. You've spent years collecting evidence that something is fundamentally wrong with you.

Here's the truth, your brain isn't broken. Most systems just aren't designed for how ADHD brains actually function.

When you start asking yourself the real questions, “Was I actually lazy, or was I trying to use a tool that doesn't work for my brain? Am I unmotivated, or is this task boring in a way that my brain literally can't generate dopamine for?” something shifts.

You realize that struggling with a mismatched setup isn't the same as being broken. That distinction changes everything.

Once you separate those two things, you can actually do something about it. You can stop wasting energy trying to become someone else and start building systems that fit who you actually are. You can stop blaming yourself for needing external structure, reminders, and flexibility on hard days because needing those things isn't a character flaw, it's just how your brain works.

The practical change isn't complicated. It's this, the next time you struggle, ask yourself, "Is this a me problem or a system problem?"

Most of the time, it's a system problem, and system problems have solutions. Your problems don't.

That one shift, from blame to design, makes everyday life feel manageable because you're finally working with your brain instead of against it.

Building multiple businesses while navigating ADHD and burnout has shaped your perspective in unique ways. What has that journey taught you about creating a life that works with your brain instead of against it?

That you can't scale something unsustainable, no matter how good it is.

My first burnout happened right after I finished my HBO in web development, a four-year degree compressed into two years while I was a single mom with a job. On paper, I was succeeding. In reality, I was surviving.

I didn't find my calling until I was 32. Web development was it, but I was learning it while surviving, not thriving.

Starting my own company, Dutch K Design, changed things. The autonomy was better. I could finally breathe a little, but then life threw curveballs.

When my mom passed away, it collided with the exact moment I was starting MindCastle. I was grieving, launching a business, and trying to figure out how to do it all while navigating ADHD, single parenthood, and the weight of loss.

That's when I realized something crucial. You can't build a sustainable business on an unsustainable life.

The turning point was asking myself hard questions, "What energizes me? What drains me? When do I actually do my best work?" And then, this is crucial, designing around those answers instead of fighting them.

For me, that meant being intentional about the work I take on. Through Dutch K Design, I do work that plays to my strengths, creative problem-solving and systems, but MindCastle, that's my dharma, as Jay Shetty would say. It's the passion project close to my heart because I genuinely believe I can make a difference in how people see themselves and their ADHD.

That's what drives me.

That's the real lesson. Your business model, your daily schedule, and your systems should all be designed around how you actually work, not around how you think you should work.

That's what I help people do through MindCastle because every ADHD brain is different, and every toolbox looks different. There's no one-size-fits-all system.

My job is to guide people in building their toolbox, the one that actually fits their brain because if your life doesn't fit your brain, you'll burn out no matter how successful you are on paper.

I learned that the hard way.

If readers remember just one idea from this conversation, what do you hope it changes about the way they see themselves or someone they care about?

That struggling doesn't mean broken.

I want people to stop separating their ADHD from their worth. To stop believing that needing help, needing structure, or needing things to be designed differently are character flaws. They're not. They're just how your brain works.

If you're reading this and you've spent years thinking something is fundamentally wrong with you, I want you to know, it's not. You're not lazy. You're not unmotivated. You're not broken. You're just using the wrong systems.

If you're reading this and someone you care about has ADHD, whether it's your kid, your partner, or your friend, I want you to see them differently too.

Stop asking them to try harder. Stop wondering why they can't just stick with it. Instead, ask, "What system would actually work for their brain?"

Once you make that shift, everything changes. Your brain isn't the problem. The design is, and the beautiful part? Design can be changed. Systems can be rebuilt.

You don't have to become someone else. You just have to build something that fits who you actually are.

That's the permission I want to give you. That's the difference I want to make.
