For Kierkegaard, meaning is forged inwardly through personal commitment. Truth is something you live, not just understand. Friedrich Nietzsche, by contrast, looks outward and forward, urging self-creation through strength, values, and becoming. Kierkegaard asks you to stand behind a choice despite uncertainty; Nietzsche asks you to overcome inherited meanings and create new ones. One emphasizes inward responsibility, the other outward transformation.
