Looking back now, the signs were everywhere. I just didn’t know what I was looking at.

The Kid Who Couldn’t Sit Still

My dopamine addiction started early. My curiosity got me into all sorts of trouble — my father once had to pull me headfirst out of a water drain I’d fallen into. I loved pulling things apart. Putting them back together? Not so much. I once dismantled a model plane my father had spent six months building. He was not impressed.

School was a daily battle. I was sent to a boys’ boarding school from twelve to seventeen, where I was frequently in trouble, regularly went AWOL for the excitement, borrowed a teacher’s car for a lap around the block, and was expelled a week before my final senior exam. They let me sit it at another school.

What I know now: That wasn’t a bad kid. That was an undiagnosed ADHD brain desperately seeking stimulation in the only ways it knew how.

Self-Medicating Without Knowing It

In my early twenties I worked as a Qantas flight attendant for six years, travelling extensively. I drank heavily — as was common with aircrew in that era. I never missed a flight, but I flew “under the weather” more than once. While overseas, I’d allow myself into dangerous situations. I’m probably lucky to have survived some of them.

I crashed my car outside a police station. Lost my licence. Drank too much. Chased risk constantly.

What I know now: Alcohol, speed, and risk were all dopamine. My brain was doing what ADHD brains do — finding any way to feel regulated. I wasn’t weak or reckless. I was undiagnosed and unequipped.

Building Things, Breaking Things

I married at twenty-eight and took over my father’s menswear store in a small rural town. I ran it for several years and had a beautiful daughter. But I lost interest — as ADHD brains do when the novelty wears off — spent more time out of it than in it, and eventually entered into a deed of arrangement and closed the business. My marriage also failed.

What followed was a long string of ventures: photography, construction, property development. Some succeeded. Some didn’t. I was hyperfocused when excited, completely disengaged when not. I could build something from nothing — but sustaining the ordinary, the routine, the administrative grind? Nearly impossible.

What I know now: That wasn’t failure. That was an ADHD entrepreneur doing what ADHD entrepreneurs do — creating, innovating, moving on. The problem wasn’t me. It was that I had no framework to understand myself.

The Diagnosis That Changed Everything

At 46, I was finally diagnosed with ADHD.

The relief was immense. Suddenly four decades of confusion had an explanation. The impulsivity, the restlessness, the brilliant starts and abandoned middles, the self-medication, the relationships that couldn’t survive my chaos — it all made sense.

But here’s what nobody told me: the diagnosis was just the beginning.

The real work was learning to understand my own operating system. Not trying to be a PC when I’m a Mac. Not fighting my brain — working with it.

What 27 Years of ADHD Expertise Looks Like

I’m 73 now. And I want you to hear this clearly:

Late diagnosis is not the end. It’s the beginning.

In the 27 years since my diagnosis, I have:

• Lost 24kg and kept it off — I’m fitter now than I was at 50
• Built businesses that finally work WITH my brain, not against it
• Written two books specifically for adults with late ADHD diagnosis
• Helped thousands of adults stop surviving and start thriving

My books, newsletter, and resources are everything I wish someone had put in my hands at 46. They’re not theoretical. They’re built from 70+ years of living with ADHD — most of it without knowing that’s what it was.

If you’re reading this and wondering if it’s too late — it’s not. Not even close.

You were never the problem. You were just running a different operating system.

Let me show you how it works.
