Friedrich Nietzsche

The mad genius with the epic mustache who declared 'God is dead' and meant it as a wake-up call, not a celebration. Nietzsche spent his life destroying everything people held sacred, then went insane after seeing a horse being beaten (he collapsed hugging the horse, crying). For his last 11 years, he was completely mentally gone, cared for by his sister - who unfortunately twisted his philosophy to support her own nationalist agenda. His books are wild rides: poetic, aggressive, contradictory, and strangely prophetic. He predicted nihilism would plague the modern world, then offered a solution: become the Übermensch - someone who creates their own meaning without needing gods or gurus. Despite chronic illness and migraines that left him in agony, he wrote about saying 'YES' to life. That's hardcore.
