 A hero is someone who has given his or her life to something bigger than oneself. As leaders in the profession of arms, Joseph Campbell's words remind us that we lead with a deep sense of duty, obligation and responsibility. This week, in memory of our fallen heroes, their families, friends and units left behind, we take to heart the enormous personal cost of service to our nation. On this Memorial Day, we appreciate current leaders, those you have inspired, and today, those you honorably mourn. Education expands our understanding of moral obligation, as well as our capacity for empathy. Today, give yourself grace as you lead with compassion, knowing what's involved is something bigger than oneself. Lead well this week.
