In Paulo Coelho's The Alchemist, the main character, Santiago, has many fears. Santiago's main fear is failure. He frequently worries that he is making the wrong choices and that the choices he makes are negatively impacting his future and stopping him from finding his personal legend.
For example, Santiago's family wishes for him to become a priest. While Santiago considers this possibility, he ultimately knows that this is not something that will make him happy or help him fulfill his personal legend. Santiago also worries about the choice he makes to leave Fatima. He understands that in order to fulfill his personal legend, he needs to continue his quest alone, and if Fatima is supposed to be a part of his life, he will meet her again. He is unsure if he is making the right choice and hopes his choices will not fail him while pursuing his personal legend.
Through his experiences, choices, and relationships, Santiago learns to overcome his fear of failure.
