"I look back very positively on my work with Mathieu, which I engaged in after a difficult personal period that had a direct impact on my life as a professional and triathlete. Mathieu’s approach, grounded in various theoretical models and supported by concrete examples, helped me return to the essence: control the controllable. His method taught me to live in the present, without constantly worrying about actions and decisions whose outcomes are unpredictable. The coaching was tailored to my needs, and Mathieu challenges ingrained thinking patterns, resulting in valuable new insights. What makes Mathieu’s approach unique is its distinctive combination of psychology, science and creativity. It was an enriching experience that I highly recommend.”
