When we think of a manual, the idea of a book that concisely and clearly distills the essentials of a topic comes to mind. With an uncommon and provocative title, Manual to Die Happy speaks to us about life and invites us to celebrate it. French writer André Malraux pointed out that "death only has importance to the extent that it makes us reflect on the value of life." In this vein, with a clear and didactic style, Mónica Tambini Ávila proposes that we take responsibility for our own existence in the face of the inevitable: death. So, how do we prepare to die happy? Is it possible to die happy? To answer these questions, Mónica dares to share everything about her experiences, lessons, and reflections on this topic. This book challenges us to think about the purpose of our existence, our life plan, happiness, love, gratitude, forgiveness, illness, and other aspects that encourage us not to delay what needs to be done and to keep our affairs and paperwork in order. Manual to Die Happy is a challenge to free ourselves from excuses, dare to be responsible for our decisions, and thus live in happiness.
