My first customer for meinsystem.app started paying every month.
I was proud. Someone had decided that my work was worth using and paying for. They gave me positive feedback and told me, in substance, that the app helps them through everyday life.
For a moment, that felt real.
Then my mind began its cross-examination.
Is the app actually that good? Could they not use something else? Why should my app be helpful? If they knew how much I doubt myself, would they still use it? Could anyone build the same thing with AI tools? Is it worth any money at all?
I had reached a milestone I had wanted for a long time. Almost immediately, I turned it into another reason to prove myself.
This is a personal reflection, not a diagnosis or medical advice. Research can provide context, but it cannot explain one person with certainty.
The Most Important Points
- My doubt did not appear because evidence was missing. It appeared while I was looking directly at payment, positive feedback and real use.
- I cannot say that AuDHD causes my imposter feelings. I can only describe patterns that may shape how I experience them.
- Perfectionism gives me short-term relief, but it also teaches my mind that the work was never good enough.
- What helps me is separating measurable facts from the story my fear builds around them.
What the Impostor Phenomenon Means
The term impostor phenomenon was introduced by psychologists Pauline Clance and Suzanne Imes in 1978. They described high-achieving women who struggled to internalise their achievements and feared that others would eventually discover they were not as capable as they appeared.
That distinction matters to me. Ordinary doubt asks whether something can improve. The impostor feeling dismisses the evidence that I have already earned my place. Success does not settle the question. It only moves the standard.
“Imposter syndrome” is the phrase most people use, but it is not an official psychiatric diagnosis. A systematic review of 62 studies found widely varying estimates and methods. The label is not a clinical verdict or an explanation for every form of self-doubt.
My First Paying Customer Immediately Became a New Reason to Doubt
I expected my first monthly paying customer to feel like proof. It was proof: someone paid, used the app and said it helped them in daily life.
My mind still found an escape route.
Perhaps the app was not really that good. Perhaps they could use something else. Perhaps one customer did not count. The evidence stayed the same, but I changed the rules for what would qualify as enough.
Then came the most painful thought: If this person knew how many doubts I have, perhaps they would stop trusting the product.
That thought confuses confidence with competence. A customer needs the product to be useful, not its creator to feel certain every minute. Their experience does not become false because I feel insecure.
Why AuDHD Might Influence How I Experience It
I have ADHD and autism. I recognise several parts of my AuDHD experience inside this pattern, but I want to be precise: I do not know that AuDHD caused my imposter feelings.
There is early research worth taking seriously without stretching it. A 2026 study of 113 first-year students from 64 UK universities found higher impostor scores in the combined neurodivergent groups—ADHD, autism or both—than in its neurotypical group. This small, cross-sectional sample cannot tell us what all neurodivergent people experience or what caused the difference.
A separate study of 500 college students found an association between self-reported ADHD symptom severity, impostor feelings and lower self-esteem. It also measured one point in time, so it does not show causation.
What I can describe more confidently is my own experience.
My performance can vary. One day I focus deeply and build a great deal; on another, basic tasks take much more effort. Then the good work can feel like a lucky exception.
I also spent years trying to look more organised and certain than I felt. Masking with AuDHD can create a split between what others see and the effort underneath. Qualitative research on autistic camouflaging reported exhaustion and threats to self-perception. It does not prove masking creates impostor feelings, but it helps me understand why competence can feel like a performance.
When I expect criticism, the fear of exposure becomes louder. I know that sensitivity from my experience with Rejection Sensitive Dysphoria, another descriptive term rather than an official diagnosis.
These are possible influences and personal interpretations. They are not a formula for every person with AuDHD.
Perfectionism Keeps the Cycle Going
My response to the doubt was predictable: I worked on the app even more.
Improvement is part of building a product. The problem was the secret job I gave it: Make the doubt disappear. Finally make the app worthy of the money.
That job has no finish line.
I make an improvement, feel brief relief and notice the next weakness. By responding to fear with more polishing, I teach my mind that the previous version really was not enough.
Perfectionism protects me from criticism briefly, then punishes me by making every milestone provisional.
I still want to build carefully. I am learning that careful work and fear-driven overwork are not the same thing.
“But Anyone Could Build This with AI”
Could another person build a planning app with AI? Of course. That does not make this one worthless.
The value of a product does not depend on it being impossible to reproduce.
Most people do not want to turn a rough prototype into something they can trust every day. Even with AI, someone must understand the problem, make decisions, test the result, maintain the product and take responsibility when it breaks.
meinsystem.app did not begin as a random feature list. I built it because I needed a system to carry me through daily life, and I use it every day. That makes neither me nor every decision right. It means the product is shaped by repeated use and a real problem.
A customer is not paying for theoretical unbuildability. They are paying for a finished, maintained solution that helps them. AI is one of the tools used to create it; it does not erase its value.
What Helps Me: Facts Instead of Moving the Burden of Proof
When the doubt becomes loud, I try to stop debating it in the abstract. I return to four facts:
- Someone pays for the app every month. Payment is a real decision, not praise I imagined.
- The feedback is positive. The customer chose to tell me what works for them.
- The app helps in everyday life. That is the outcome I wanted the product to create.
- I use it myself every day, and it helps me. I know the problem from the inside.
These facts do not prove perfection. They prove something more useful: the app already has value for real people.
I am trying to judge progress by a standard that fits my life, not by an imaginary founder who never doubts or tires. I wrote more about that in redefining success as a neurodivergent person.
The aim is not to replace every difficult feeling with forced confidence. It is to stop allowing a feeling to erase every piece of evidence.
What You Can Try Today
Take one achievement you keep minimising and divide a page into two columns.
On the left, write only what can be observed:
- What happened?
- What did another person actually do or say?
- What result can you point to?
On the right, write what your doubt added:
- “They were only being nice.”
- “Anyone could do this.”
- “It will count when I achieve the next thing.”
Do not try to make the right column disappear. Ask one narrower question: What evidence would I accept if this achievement belonged to someone I care about?
Then apply the same standard to yourself for today. Not forever. Just today.
Frequently Asked Questions About Imposter Syndrome and AuDHD
Is imposter syndrome an official diagnosis?
No. It is a common name for the impostor phenomenon, not a diagnosis in the DSM or ICD. It describes difficulty internalising success and fear of being exposed as a fraud. The thoughts can still cause serious distress.
Do people with ADHD or autism experience imposter feelings more often?
Some student studies found higher scores in neurodivergent groups or an association with ADHD symptom severity. The evidence is limited, the samples are specific and the research is cross-sectional. It cannot establish causation or speak for every autistic person or person with ADHD.
Does doubting myself mean my work is not good enough?
No. Doubt may be a signal to inspect something, but it is not a quality assessment. Ask whether the work solves its problem, whether people use it and what feedback they give. Something can need improvement and already be valuable.
How can I stop perfectionism?
I do not stop it by demanding that I become relaxed. I try to define “done” before fear changes the standard: what problem am I solving, what evidence would show that it works and which improvements can wait? If perfectionism controls your life, professional support may help you understand and change the pattern.
When should I seek support?
Consider professional support if the fear causes persistent distress, stops you from working or resting, or is tied to anxiety, depression or burnout. Seek urgent local help if you are in immediate danger or may harm yourself. A blog post cannot assess your situation.
You Do Not Need to Be Free of Doubt to Build Something Valuable
I would like to say that my customer’s feedback removed the doubt. It did not.
What changed is that I see the movement now: something good happens, my mind shifts the burden of proof, and perfectionism offers more work as the price of legitimacy.
I do not have to pay that price every time.
My doubts are real feelings, not secret information about the product. The customer’s experience still belongs to them. The help and the payment still count.
If you want to see the system that grew from that need, you can visit meinsystem.app. But the point I want to leave with you is larger than my app.
You do not need complete confidence before your work is allowed to matter. You can feel uncertain and still have built something useful. The doubt may come with you. It does not get to erase the evidence.
