Flexibility is one of the most important qualities when it comes to mastering our complex world. It is essential to cope with the diverse upheavals and disruptions of the 21st century. At the same time, the goal is to develop an inner stability that grounds us firmly in our lives while also making us flexible enough to adequately meet the challenges of everyday life. What we need, therefore, is inner stability through flexibility. In his new book, bestselling author Marco von Münchhausen outlines four key factors that provide us with inner stability: the ability to maintain balance in life, the capacity to manage everyday stress, a good lasting resilience, and the art of continually stabilizing oneself in daily life. The book presents a kind of psychological buffet.
