No question has probably been asked more often than this one! Millions have asked it in earlier times, millions do it today and millions, still unborn today, will ask it in the future. In the past, countless thousands would have given their possessions for a safe answer. But in today's world, which is characterized by the devaluation of all values, stress-ridden people do not even find the time to pursue this question. This means that the path to a fulfilled life does not necessarily lead through external changes, but through a transformation of our inner self. It takes courage and self-awareness to commit to this inner work, but the rewards are profound. Well, there is an answer. There is one big, simple rule! If you make this the supreme guiding principle of your life, then your life will be a string of successes. One thing is for sure, by far the majority of humanity is looking for the answer in the wrong ways. Most people do not do so with will and intention, but simply because they do not know the right way. In this book lies the true secret of life, and that is what the whole world is looking for.
