For those who don't know me, I'm a U.S. Naval Academy graduate and former submarine officer turned small business executive turned military-to-corporate recruiter. I've led operations and engineering teams underwater, Sales teams in business, and placed 400-plus military leaders into corporate roles as a recruiter. Leadership has been the throughline of every chapter. Here's one of the clearest lessons I ever learned on the subject — and it came from a guy who taught me everything about leadership by being terrible at it.

The Best Manager I Ever Served With

Back in my submarine days, there was one guy I served with who taught me that leadership and management are completely different sports. Not because he was a good leader. He wasn't. But because he was a stellar manager.

Thirty years in the Navy had taught him how to manage. And he loved his job. He could navigate a submarine and run an efficient department like nobody's business. Watch, qualifications, inspections — the man knew every system and process on that boat better than the technical manuals did.

But he was miserable to work for.

I personally watched him melt down on subordinates for making mistakes more times than I can count. Yelling. Belittling. Making it clear that a mistake meant something was wrong with you, not just the work. In his mind, his job was making sure the department upheld certain standards. And on a submarine, that mindset didn't come from nowhere.

Standards Weren't the Problem

He wasn't wrong that standards matter. On a boat, especially — where a mistake can cost lives — standards aren't optional. I understood why he acted the way he did. I still understand it, all these years later.

But in enforcing them the way he did, everyone in his department hated him. Not disliked. Hated. He was a ticking time bomb nobody felt comfortable around, and working under his "leadership" was about as close to hell as you could get without being burned by the flames.

People didn't come to him with problems. They hid them. They fixed what they could quietly and prayed the rest never surfaced on his watch. That's not a department running well. That's a department running scared, which looks the same from the outside right up until it doesn't.

His Management Made Him a Master Chief. His Leadership Made Him Unapproachable.

That's the whole lesson in one line. He climbed every rung the Navy had to offer because he could manage systems. But he never built the one thing that makes a team actually want to follow you.

I've thought about that contrast more times than I can count since I left the Navy. Management is what gets you promoted. Leadership is what makes people follow you somewhere hard, voluntarily, because they trust you'll get them through it.

Why This Distinction Matters More in Business, Not Less

You'd think a business without life-or-death stakes would have more room for a manager like him. It's the opposite. On a submarine, people can't quit. They're stuck with a bad leader until the next duty station, whether they like it or not.

In business, they can leave. And they will.

I watched this play out firsthand years later, running Sales, Operations, HR, and finance for a small business that scaled from 3 employees to 30 in four years. The employees who stayed through the hardest stretches weren't staying because the paycheck was great. They stayed because they trusted the people leading them — not because those people never made mistakes, but because they never hid behind rank or title to avoid owning one.

Leadership Is a Skill, Not a Personality Trait

Leadership is the art of building trust, earning respect, and creating a culture of accountability. It's a skill you build deliberately, not something you're born with — and it's essential to building, and more importantly keeping, a high-performing team together.

If people don't feel safe approaching their leader, they won't just hide problems from you. Eventually, they'll leave. It doesn't matter how well you manage them on paper. A perfectly run department with a leader nobody trusts is a department slowly bleeding out its best people, one quiet exit at a time.

Management might be the engine, but leadership is the glue.

The Difference Shows Up in the Small Moments

You don't see the management-versus-leadership gap in the big speeches or the annual reviews. You see it in the small moments nobody's grading. How someone reacts when a junior person makes a mistake in front of the whole team. Whether they ask "what happened" or "whose fault is this." Whether the room gets quieter or more honest when they walk in.

My old boss failed almost every one of those small moments, over and over, for years. He wasn't a bad person. He genuinely believed he was doing right by the mission, and in a narrow sense, he was — the department ran, the boat stayed qualified, the numbers looked fine on paper. But he never once asked himself what it was costing the people who had to deliver those numbers for him.

That's the trap management-without-leadership sets. It works, right up until it doesn't.

Leadership You Can Actually Measure

If you want a real test for whether you're managing or leading, here's the one I use now. Ask yourself: when something goes wrong on my team, do people come to me immediately, or do they try to fix it quietly first and hope I never find out?

If it's the second one, you don't have a management problem. You have a leadership problem, and no amount of process improvement will fix it.
