In February, my mother died unexpectedly. Within a matter of hours, my calendar for the week was cleared—meetings canceled, commitments postponed, responsibilities either delegated or delayed. That included my article for the last issue of the Shed Business Journal. Things that had felt important just a day before were suddenly easy to move. In the middle of that disruption, a question surfaced that stayed with me: where did all of that go?

Because the work didn’t disappear. It shifted. It moved onto someone else, or it was pushed into the future where I would eventually have to deal with it. That experience clarified something I think many of us intuitively know but rarely stop to consider—when there is no margin, commitments and responsibilities are still present and must be addressed. And when something unexpected enters our lives, it doesn’t remove the existing load; it simply redistributes it.

Most leaders I know are operating at or near full capacity. Their calendars are full; their responsibilities are significant; and their days are defined by a constant stream of decisions, conversations, and problem-solving. In many ways, this pace is normalized, even rewarded and celebrated. It can feel productive and responsible to be fully engaged at all times. But the reality is that a leadership approach built on 100% capacity is not strong—it is fragile. When everything is full, there is no room for the unexpected, and the unexpected always comes.

Margin, at its simplest, is the space between our load and our limit. It is the gap between what we are carrying and what we are capable of carrying. Most of us live very close to that line, and sometimes just over it. But that small amount of space—when it exists—is what gives us the ability to respond thoughtfully instead of reacting under pressure. Margin creates breathing room. It provides flexibility. It allows a leader to absorb disruption without everything else immediately straining under the weight.

We already understand this principle in other areas of life. Financially, for example, we know that if we spend everything we earn, we are one unexpected expense away from stress. But when we consistently spend less than we make, we create options. We create resilience. The same is true in engineering, where systems are built to handle more than the expected load; and in athletics, where recovery is intentionally built into training so that performance can be sustained over time. Margin is not waste; it is preparation.

When leaders operate without margin, the effects show up in both subtle and obvious ways. There is often a constant sense of pressure, even when nothing is technically wrong. Everything feels tight, and leaders have little tolerance for disruption. As time and energy are consumed by what is immediately in front of us rather than what is most important, our leadership becomes reactive rather than proactive. And perhaps most significantly, the entire system becomes fragile. It may function well under normal conditions, but it lacks the ability to absorb stress when something unexpected happens.

That was my experience in February. Stepping away for a week was necessary, but it created a ripple effect. The work did not go away; it simply moved. And without margin, such movement creates pressure somewhere else. When everything is already full, there is no easy place for that pressure to go.

Margin is not just a conceptual idea; it shows up in very practical ways in a leader’s life. Three areas in particular deserve attention: finances, time, and energy. Each of these represents a different dimension of capacity, and each plays a critical role in a leader’s effectiveness.

Financial margin is perhaps the most straightforward. It is the discipline of spending less than you make and building in a buffer for the unexpected. In a business context, this includes profitability, cash reserves, and a thoughtful approach to expenses. Without financial margin, even small disruptions can feel significant. A delayed payment or an unplanned cost can quickly escalate into a stressful situation. But with margin, those same challenges are manageable. Financial margin does not eliminate problems, but it changes how those problems are experienced and addressed.

Time margin is often more difficult to establish, particularly for leaders who feel the weight of many responsibilities. Having time margin requires intentionally leaving space in the calendar rather than filling every available moment. This can feel counterintuitive, especially in environments where responsiveness and availability are valued. However, a completely full calendar leaves little room for thoughtful leadership. It limits the ability to think strategically, to engage in meaningful conversations, and to respond effectively when something unexpected arises. Time margin creates the space necessary for leaders to lead, rather than simply keep up with activity.

Energy margin may be the most overlooked and, at the same time, the most critical. Leadership is not just a function of time; it is a function of energy. Every decision, conversation, and challenge draws from a leader’s physical, emotional, and mental reserves. When those reserves are depleted, the quality of leadership declines. Decisions become more reactive, patience wears thin, and clarity diminishes. Burnout is not simply the result of working too much; it is often the result of expending energy without sufficient replenishment. Without energy margin, a leader may still be present, but he is unlikely to be effective at the level required.

Beyond these individual areas, there is a broader principle that applies to leadership as a whole. Effective leadership requires margin in overall capacity. If a leader is operating at 100% of his capacity, he is only able to handle what has already been planned. There is no capacity to invest in extras. Yet leadership by its very nature involves responding competently to the unplanned. Challenges arise, opportunities emerge, and people require attention in ways that cannot always be anticipated.

When I stepped away after my mother’s death, my team and clients had to adjust. Others stepped in, priorities shifted, and some of the work was redistributed. That adjustment is only possible when there is margin somewhere in the system. If every person is already operating at full capacity, any disruption creates strain across the entire organization. In that sense, margin is not just a personal discipline—it is an organizational necessity.

Building margin is simple in concept but challenging in practice. It requires a willingness to do less than we are capable of doing, to leave space unfilled, and to say no more often than may feel comfortable. It involves protecting time and energy with intention and resisting the natural tendency to fill every available gap. It also means building margin into teams and systems, rather than expecting constant maximum output from everyone at all times.

The goal is not to do less just for the sake of doing less. The goal is to create the capacity to respond when it matters most. Life has a way of demanding more than we anticipate, whether through challenges, opportunities, or personal circumstances. When that moment comes, margin is what allows a leader to respond with clarity, presence, and effectiveness rather than stress and reactivity.

In the end, margin is not a luxury for leaders—it is a necessity. Margin is what allows us to absorb the unexpected, to care for what matters most, and to lead well over the long term.
