The most valuable leadership advice I've ever received wasn't a tip, a principle, or a lesson learned. Instead, it was a question that challenged me to reflect deeply on my values as a leader.

When I was a captain, a peer asked, “Would you rather be thought of as a great leader of an average unit, or an average leader of a great unit?"

The either/or nature of his question forced me to examine and prioritize my underlying motives as a leader. Which was more important to me - my own reputation, or that of my subordinates and our unit? Both mattered greatly, but I wasn't sure which carried more weight. I wasn't even sure if the distinction mattered.

His question spurred a habit of reflection that produced a powerful new lens through which I could view and assess myself and other leaders.

Keeping his question in mind, I began noticing troubling subtle indicators of my own values-in-action. For example, after my unit succeeded on a particularly challenging mission, I was generous in giving my subordinates public recognition when I spoke to them, but heard myself using “I” much more often when briefing my superiors. I realized I wanted my raters to note my role in the mission's success, even if doing so diminished the credit given to the rest of my unit.

I realized the best leaders were those who seemed to care least about receiving credit. They were truly servant leaders, sacrificing not only for our country but also for their subordinates.

One practical outcome of my reflections has been that I strive to put as much effort into my final 90 days on a job as I do on the first 90 days. I want to be a leader who helps my successor and my organization succeed long after I'm gone.

I am grateful that my friend had the courage and wisdom to ask me that challenging question. He catalyzed a process of reflection that has led to increased self-awareness, empathy, and effectiveness, and has enabled me to discover things about myself that no one else could teach me.

In appreciation for his priceless gift, I want to pass it on. So now I ask you, “Would you rather be thought of as a great leader of an average unit, or an average leader of a great unit?"
