Lived experience
Why I built Rising with Atlas
At 17, I entered the Cyprus equivalent of BUD/S training with a severe injury. I could barely grip with my right hand. Grit matters, but so do circumstances. Effort alone does not guarantee success. That experience taught me what it means to suffer and to show up broken, even when success is out of reach. Because showing up still means something.
At 22, I began a decade-long fight to rebuild my health. My weight fell from 80 kilos to 59. Eating became painful. I went from expert to expert across Cyprus and the UK, searching for answers.
Rebuilding meant bringing together biology, nutrition, systems thinking and lived experience. The Self Matrix, the CORE Compass and Excellence Nexus grew out of that work: frameworks I forged to survive, then thrive, and now, to serve.
Beyond the work
I’m a lifelong martial artist. I’ve trained with Bill “Superfoot” Wallace and was guided and taught for many years by Constantinos Archontides during the early emergence of Brazilian Jiu-Jitsu in Cyprus.
Before the age of 20, I was selected four times to represent Cyprus at the European Youth Parliament.
The Six Primes
One life.Every part powers the whole.
To thrive, life must be cultivated as a whole: body, mind, heart, soul, wealth and impact. Each part strengthens the others. Each one is essential. That is the thinking behind Excellence Nexus and the work I share through Rising with Atlas.
A powerful body gives you the energy to pursue your ambitions. A clear mind helps you make better decisions. Wealth gives you choices and freedom over your time. Deep relationships give you people to share your life with. Purpose directs your efforts, and impact carries their value into the lives of others. Each domain shapes the next, subtly, powerfully, and inevitably.
These things deserve your attention together. The discipline, imagination and care you bring to your work belong in your health, relationships and the rest of your life too.
I write and create practical programmes for people who want to become wildly successful, feel fully alive and give the people they love the best of themselves.
Through my essays, books and courses, I bring science and strategy to the decisions that shape your days: how you care for your body, direct your mind, build wealth, nurture your relationships and pursue work that matters.
