“That’s just how I’m wired.”
How many times have you said that—or heard someone on your team say it?
Here’s what neuroscience has proven: it’s not true.
Our brains can change at any age. And once you understand that—really understand it—everything shifts. What you believe is possible for yourself, for your team, for your leadership.
The proof? London taxi drivers.
In 2000, researcher Eleanor Maguire studied their brains. To qualify as a London cabbie, drivers must pass “The Knowledge”—one of the world’s hardest memory tests. They spend years memorizing every street, landmark, and route in London’s 25,000-street maze.
When Maguire scanned their brains, she found something remarkable: their hippocampus (the part responsible for spatial memory) was significantly larger than average. And it kept growing the longer they drove.
Their brains physically reshaped through experience and practice.
I have long claimed to have a terrible sense of direction. My husband jokes that I could get lost in our own house. For years, I told myself, “That’s just how I am.”
But neuroplasticity taught me something important: if it truly mattered to me, I could change it. I could train that skill like the taxi drivers did.
I choose not to—it’s not a priority for me. But that choice comes with responsibility. Because if something truly matters, I have the ability to change it.
And here’s where this gets powerful for leaders:
That chronic interrupting habit? Not fixed. 🔓
That reactivity under pressure? Changeable. 🔄
That fear response that hijacks your best intentions? Trainable. 💪
I see this all the time. A leader who’s been interrupting people for 20 years can still learn to listen. A leader who has been claiming stage fright their whole career can learn to take the stage with calm confidence. It takes practice and awareness, but the brain will adapt.
Every time you pause before reacting, breathe through stress, or choose intention over impulse—you’re literally rewiring your brain.
That’s mindful leadership: using awareness and practice to shape not just what you do, but who you become.
So I’ll ask you: What have you been telling yourself is “just how you are”?
And more importantly—is it actually true? Or is it just a story you’ve been repeating?
Because your brain is more adaptable than you think. The question is: what do you want to wire it for?
This week, notice when you say, “That’s just how I am.”
Then ask yourself: Is it? Or could it change if it mattered enough?
That’s where transformation starts.
