This book examines lifelong learning in the context of the increasing digital enrichment of our lives. Learning and working environments are changing, along with the requirements for initial training, further education, and professional development. More and more knowledge is becoming available, while the time frame in which it remains relevant is shrinking. Lifelong and digital learning is thus not only a necessity for individuals but also essential for companies, industries, and entire regions to remain competitive. The author addresses the question of how and why we learn based on theoretical approaches from psychology, pedagogy, and economics. Building on this, he investigates the significance of online training in tourism through qualitative expert interviews.
