Never doubt that you can change history. You already have.

The line is an exhortation against political or personal fatalism: it insists that individuals—especially those who feel powerless—are already participants in shaping the historical record through their choices, labor, and resistance. The first sentence challenges the common belief that “history” is made only by famous leaders or singular events; the second reframes agency as cumulative and ongoing, suggesting that even small acts have already altered outcomes and narratives. Read this way, the quote functions as motivational rhetoric aimed at sustaining activism and self-trust, emphasizing that change is not merely possible in the future but is a fact of lived experience.
