Dmitry Khadikov is an entrepreneur, marathon runner, and mentor to business owners. He is the founder of the dental clinic «Atmosphere» in Ryazan, one of the leading dental clinics, and the author of the projects «BusinessWeekend», «Vector», and «Personality 2.0». The author's method «CORE» helps achieve a state of wholeness, where life is not fragmented into separate parts, but is structured into a unified system, where all spheres – or, as the author calls them, «holistic projects» – support each other. «CORE» is a way to return to an inner center and create a foundation in which a person becomes the main resource – not through constant effort, but through inner wholeness and «composure». The method is based on a model that unites energy, work, and money, roles and relationships. When these elements are disconnected, overload, chaos, and internal tension arise. When they are connected, clarity, stability, and energy for life emerge. This book is about how to build such a system within yourself and live from a state of foundation that defines the quality of decisions, actions, and life in general.
