This introduction presents an overview of the key concepts discussed on the subsequent chapters of this book. The book seeks to go beyond the tick box-style nature of 'curriculum vitae building', and offers thoughtful guidance and advice from writers with real-life experience as, or teaching, students. It outlines two common examples - establishing a group or campaign and organising an event, told through the experience of running a conference. The book focuses on the opportunities medical school that offers for international health exchange and learning told through medical electives, global health research and internships. It includes a diverse collection of perspectives and insights from both high- and low-resource settings. The book covers an area of increasing interest - international mobility in medical training and practice. It describes career perspectives from eminent clinicians who have combined the demands of clinical practice with exemplary leadership in their field.
