Friedrich Nietzsche's personal hardships greatly influenced his philosophical outlook, particularly his struggles with mental health and isolation. These experiences prompted him to challenge conventional morality and explore themes of existentialism and the will to power. The rejection he encountered in relationships and his battles with physical illness led him to reflect on the nature of suffering and its role in personal growth. Nietzsche's concept of the Übermensch, or 'overman,' arose from his belief in transcending conventional morality, advocating for individual responsibility and self-creation. His work encourages embracing life’s struggles as opportunities for profound personal transformation.
