Last week, something unexpected happened during one of my gym sessions. A few months ago, I went through a health situation that required a long recovery. Returning to the gym meant starting over. Walking before running. Lifting lighter weights. Respecting what my body needed in that season. At first, those limits were real. They had to be.
Before that period, running at 12 kilometres per hour on the treadmill was part of my normal routine. During recovery, I rarely went beyond 4 kilometres per hour. That was exactly where I needed to be. But last week, almost on a whim, I increased the speed. I expected my body to protest. It didn't. A few days later, I tried again. The same thing happened. I wasn't tired. I wasn't struggling.
I simply realised I could do far more than I had been allowing myself to do, and that's when it hit me. I wasn't being limited by my body anymore. I was being limited by an assumption I had never stopped believing.
The temporary limit had quietly become a permanent rule. My body had moved on. My thinking hadn't. Standing on that treadmill, I couldn't help but wonder: How many leaders are doing exactly the same thing? Not in the gym. In the way they lead.
Some limits begin with a difficult experience. A presentation that didn't go well; A promotion that felt overwhelming; a business that failed; feedback from a manager that lingered longer than it should have; a decision that didn't produce the outcome we hoped for. At the time, those experiences teach us something important. The lesson is useful; the limit isn't.
Yet years later, we continue making decisions as though those old circumstances still define what we're capable of. A leader who once trusted the wrong person struggles to delegate. A leader who was criticised for speaking up begins choosing silence over contribution. A founder whose first bold decision failed starts believing that caution is the safest strategy.
None of these leaders are responding to today's reality. They're responding to yesterday's experience. Experience is one of leadership's greatest teachers; it can also become one of its greatest prisons.
The longer we lead, the easier it becomes to mistake old experiences for permanent truths. We stop testing assumptions; we stop exploring; we stop asking whether the boundaries we accepted years ago still belong in today's decisions. Without noticing, we begin leading inside limits that no longer exist.
One of the most important leadership disciplines isn't learning more. It's questioning more. Not asking: "Can I do this?" But asking: "Is this still true?" Those are very different questions. One assumes the boundary still exists, but the other dares to test it. Growth usually begins when curiosity returns, when we become willing to question the stories we've been telling ourselves, and when we recognise that our minds are designed to protect us, but not always to update us.
Sometimes the greatest barrier to growth isn't capability. It's familiarity.
Every leader carries invisible limits. Some are real. Others expired years ago. The challenge is that our minds rarely tell us the difference. They simply continue following instructions we gave ourselves in a different season. Every season teaches us something. The danger isn't learning the lesson; the danger is continuing to live by it long after the season has changed.
Sometimes growth is about discovering that you've been capable of more for much longer than you realised.
So before asking yourself what you need to learn next, I suggest asking a different question: Which limits am I still obeying that no longer exist?
