In 1996 he has started to invest on Real Estate in Belgium and since then has been sharing experiences as investor in private housing with Fortune de Briques at Éditions Racine.

In 2001 he worked on the “Motivation Wheel”, a psychological tool for a circular analysis of human characteristics, such as behavior, values, concerns, needs and desires for inner fulfillment. This work explained about an interpretative framework for connecting “doing” and “being” through aspirations, fears and internal strengths. The model was designed to be used for corporate aspects, such as corporate culture development, time management and values, evaluation of intangible assets, coaching and individual’s mentoring. The 7D-Value approach, based on the 7 levels of value is also used to map excellence and potential of individuals.

Later, in 2005, he published the book “The Value of Time” and the “Die Werte der Zeit” edition by the publisher Swinti Verlag GmbH, and “La Valeur du Temps” in 2006 by Éditions Racine. The book was a work of philosophy and psychology applied to management and life. It gave a different perspective to the Greek nations of chronos, kairos and aion in a way to find openness of self to life. Today, he is a consultant and trainer of this subject at the Free University of Brussels and at the University of Louvain-la-Neuve (Louvain School of Management).

De Kemmeter has started in 2006 a network of reflection and innovation on human development and societal development, named UHDR (Universal Human Development and Research). This network of collaborators has been creating tools for development of human potential, self-connection and experiential conscious mentoring, in collaboration with medics, sportsmen, companies, universities, philosophers and therapists.

In 2008, he has founded UniverseCité UHDR (UHDR UniverseCity) of Sustainable Human Development, which has the goal of bringing “soft skills development” based on concepts of collective intelligence and experimental learning. In his research, he works on transdisciplinarity, on systems theory, systemics, prospective, on sociology and applied psychology.
