Mentorship: Developing People Who Outgrow You

Welcome to another week with Boundless.

Before we jump into this week's topic, I want to take a moment to welcome our newest Boundless Premium Members who are joining our June 2026 Cohort.

Over the next twelve months, these leaders will work through a structured leadership development journey alongside a certified leadership coach, a Core Group of peers, and a curriculum focused on twenty-four essential leadership principles. They'll challenge each other, learn from each other, and gain practical tools they can immediately apply within their teams and organizations.

One of the things that makes Boundless special is that leadership isn't learned in isolation. Growth happens through conversation, accountability, reflection, coaching, and application. We're excited to have this group joining the Boundless community and look forward to watching their leadership journey unfold over the coming year.

Now, let's talk about mentorship.

One of the most important questions a leader can ask is surprisingly simple:

What happens to the people who work for me?

Not while they're on my team.

After.

Do they become stronger leaders? Do they take on greater responsibility? Do they earn promotions, expand their influence, and grow in confidence because they spent time working alongside me? Or do they simply stay productive contributors who perform well but never quite reach their potential?

The answer to that question says more about a leader than almost any performance metric ever could.

Many managers spend years learning how to drive results, improve performance, manage projects, and hold people accountable. Those are all important skills. But eventually every leader reaches a point where success becomes less about what they personally accomplish and more about what they help others become.

That's where mentorship begins.

One of the challenges of leadership is that our best employees often become incredibly valuable to us. They're dependable. They require less supervision. They make good decisions. They solve problems before they become emergencies. They help us hit goals and make our jobs easier.

And because of that, managers sometimes face a temptation they rarely talk about.

They start thinking about how much they need that person.

When a top performer begins expressing interest in a promotion, a new challenge, or a bigger opportunity, the manager's reaction matters. Some leaders immediately begin thinking about how they can help that person grow into the next role. Others quietly start calculating what life will look like without them.

Neither reaction makes someone a bad leader. It's human nature. But great leaders eventually realize something important:

The goal isn't to keep talented people forever.

The goal is to prepare them for what comes next.

In Multipliers, Liz Wiseman describes leaders who make the people around them smarter, more capable, and more confident. These leaders don't measure their success by how dependent others become on them. They measure success by how capable others become because of them.

That's a profound shift in thinking.

Weak managers unconsciously build teams that rely on them for answers. Strong mentors build people who can think, decide, and lead without them. One approach creates followers. The other creates future leaders.

When I think about the people who had the greatest influence on my own career, what stands out isn't the advice they gave me. What stands out are the opportunities they trusted me with. They invited me into conversations I wasn't expecting to be part of. They gave me responsibility before I felt completely ready. They challenged my thinking, expanded my perspective, and helped me see possibilities that I hadn't considered for myself.

That's what great mentors do.

They see potential before it becomes obvious.

They don't simply develop skills. They develop confidence.

And confidence often grows through experience rather than instruction.

This is one reason mentoring is different from training. Training teaches someone how to perform a task. Mentorship helps someone prepare for a future they haven't reached yet. Training focuses on competence. Mentorship focuses on growth.

The distinction matters because many managers spend most of their time discussing current responsibilities. They talk about projects, deadlines, performance, and priorities. Those conversations are necessary. But mentors also make time for different conversations.

They talk about aspirations.

They talk about strengths.

They talk about weaknesses.

They talk about long-term goals.

They talk about opportunities that may not even exist yet.

Most importantly, they help people think beyond the role they're currently sitting in.

Michael Bungay Stanier explores this idea in The Coaching Habit, where he encourages leaders to ask more questions and provide fewer answers. Great mentors aren't valuable because they always know the solution. They're valuable because they help people discover solutions for themselves.

That approach develops judgment.

And judgment may be one of the most important leadership qualities a person can develop.

Processes can be documented. Skills can be taught. Technology changes. Industries evolve.

But the ability to assess a situation, think critically, navigate uncertainty, and make sound decisions becomes increasingly valuable as people move into larger leadership roles.

Strong mentors understand this. They don't just tell people what to do. They help them learn how to think.

They also understand that growth rarely happens inside someone's comfort zone.

Many leaders say they want to develop their people, but development requires stretching people beyond what feels comfortable. Sometimes that means assigning a project that feels slightly too large. Sometimes it means asking someone to lead a meeting, present to senior leadership, manage a difficult conversation, or take ownership of an initiative they've never handled before.

Those experiences can be uncomfortable.

They're also where growth happens.

Years later, most people don't remember the routine assignments that filled their calendars. They remember the moments when someone trusted them with something bigger than they thought they were ready for.

That's often where careers change direction.

One of the most overlooked responsibilities of a mentor is opening doors. A recommendation, an introduction, a networking opportunity, or an invitation into the right room can alter the trajectory of someone's career. Great leaders understand that their network isn't simply an asset for themselves. It's something they can leverage to create opportunities for others.

And that's why mentorship matters so much.

Long after projects are completed and organizational charts change, people remember the leaders who invested in them. They remember the manager who believed in them. They remember the conversation that challenged them. They remember the opportunity that accelerated their growth.

In many cases, they become that kind of leader for someone else.

That's the ripple effect of mentorship.

As you think about your own leadership this week, consider these questions:

• Who on my team has the potential for more responsibility?
• What am I doing to prepare them for it?
• When was the last time we talked about their future instead of their current role?
• Am I creating followers, or am I developing future leaders?

Because at the end of the day, leadership isn't measured by how many people report to you.

It's measured by how many people grow because they did.

Onward.
