A leader's greatest insights often come from frontline employees, not the boardroom. Despite being an expert advisor for decades, the UniCredit CEO credits the bank's successful transformation to listening to "people in the branches." This humility uncovers the most effective strategies.

When leading a complex, member-driven institution like the IMF, the primary responsibility is not to impose one's personal beliefs. Instead, effective leadership involves understanding and serving the collective needs of the membership, even in a world with increasing complexity and divergent interests.
