Professional life constantly presents us with difficult decisions, desired or unwanted changes, conflicts, phases of over- or under-challenge, and much more. Those who want to be successful today should possess skills that help us master these challenges: self-leadership techniques, flexibility, motivation for change, courage, and a sense of the situation. Fortunately, these skills are inherent in each of us! This book aims to help you unlock and optimize them. You can read it in its entirety or refer to it whenever you face a specific problem: Part 1 provides insights to analyze your motives, strengths, weaknesses, and expectations, and to sharpen your goals. The chapters in Part 2 are based on typical situations in a professional career, from career choice to conflict situations and health issues.
