This book was born of a simple conviction: Mbujimayi's true wealth is no longer limited to the mineral diamond; it now lies in the ingenuity of its youth and women. Every day, in the neighborhoods of Bipemba, Kanshi, Dibindi, Muya, Diulu and beyond, I've seen ideas turn into small businesses, constraints into solutions, dreams into concrete forms. I wanted to gather these often invisible weak signals into a useful, accessible and mobilizing narrative.What this book is: a guide rooted in reality, nourished by observation in the field, dialogue with entrepreneurs and the experience of accompanying projects in Mbujimayi.What this book is not: an exhaustive academic thesis. It does not claim to cover or solve everything. Rather, it offers guidelines, examples and simple tools to help you "get on with it".
