If you're lacking self-confidence this book could help you achieve your goals. Ridiculed by his parents during his childhood, Nahuel Millaman, a seventeen-year-old Mapuche boy living in Santiago, Chile is extremely shy and lacks self-confidence. When his girlfriend, Calfuray Cayancura, informs him that she is pregnant, the prospect of parenting a child is too daunting and he runs away hoping to regain his self-confidence and return before the child is born. Nahuel travels to the Valdivian Forests to seek help from an old Mapuche Machi or Sharman, Sayen Melilan, who explains the formula needed to restore Nahuel's self-confidence. Nahuel returns to Santiago. Using the formula Nahuel finds employment, gains an accountancy diploma and is employed as an accountant. He returns to Calfuray but she tells him that she miscarried and is living with another man. Nahuel focuses on his career, still deeply in love with Calfuray. He receives regular promotions but begins neglecting Machi Sayen's formula and his self-confidence wanes. Nahuel resigns from his job and starts his own accounting practice. The business fails and he moves to Valparaiso where he begins to use Machi Sayen's formula again and gains employment. Calfuray's partner turns out to be a wife-beater and she deserts him and flees Valparaiso, still very much in love with Nahuel. Both Nahuel and Calfuray hope to be reunited but after so many years apart the chances of this happening are remote.
