“What would the world be without activists? What would become of human nature without activists? Not because activists are perfect, or because they’re always right, or because they’re übermensch who never fail… None of that. It’s because activists aren’t looking for their own benefit - they’re fighting their souls off for a handful of dreams. At the end of the day, human progress requires that there be people who find happiness in living their lives in the service of humanity. Because becoming an activist means bearing a heavy burden - it’s about finding meaning in fighting for transcendental freedom” - Pepe Mújica Cordano, former President of the Republic of Uruguay
