Step-by-step explanation:
The question asks about the most important personal development strategy for effective global leaders.
While various strategies could be effective, one of the most impactful for global leadership development is overseas assignments.
Such assignments help leaders learn how to navigate different cultural landscapes, manage diverse teams, and gain a broader understanding of global markets and operations.
Through immersive experiences, they adapt to new environments, encounter real-world challenges, and develop a global mindset, which is crucial for leading across borders.
Moreover, leadership development is not just confined to international contexts. Issues such as preparing and delivering the first State of the Union address and nominating and confirming a cabinet are critical tasks for new presidents and can shape their leadership.
Additionally, the concept of expressive leadership speaks to the ability to influence and inspire, often seen in settings where leaders must foster strong relationships and morale, such as a director of a summer camp for chronically ill children.
