For most of my life, I was a thinking-first person. I studied engineering at Cambridge, worked in consulting and venture capital, and helped scale fast-growing technology companies. I reached many of the goals I thought I wanted, but ultimately they didn’t leave me more energized or fulfilled.

My instinct was to solve it by thinking more. But logic and analysis were not getting me closer to an answer. Eventually, I decided to make a bigger change and left my previous life behind.

I travelled widely, from hiking in Iceland to Carnival in Rio to festivals in South Africa. These experiences felt good in the moment, but ultimately did not create a lasting change in energy. Somewhere along that journey, my exploration started turning inward.

I ended up on a silent meditation retreat in South Korea. After several days of meditation, something shifted: my mind became completely quiet. For the first time, I experienced that I was not my thoughts and could create distance from them. The teacher left me with four words that stayed with me: Think less, feel more.

That experience opened up a different way of navigating life. I learned to pay more attention to feeling and intuition: what gave me energy, what pulled me in and what felt right even when I could not fully explain why. That shift deepened through experiences like spending time with people who saw life completely differently, going deep into breathwork, staying in monasteries, multiple ayahuasca ceremonies, days alone in the desert and many other experiments in how to live.

Along the way, I began to see how many of my earlier goals had been shaped by beliefs, fears and expectations I had absorbed from others and carried forward largely unquestioned. I came to call this interference. Beneath it was something quieter: a sense of what gave me energy and felt genuinely my own. I called that signal.

As I learned to hear that signal more clearly, I realized that part of my signal was to create things that could genuinely help others. Interference is one of them: the book I wish I had when I started this journey. It combines the story and framework with practices to help you experience the ideas for yourself, because for me, experience was the real unlock.
