The water strider is an insect that spends its entire life on the surface of water. Weighing almost nothing, its legs are covered in thousands of microscopic hairs that trap air and distribute its weight so precisely across the surface film that it never breaks through. It neither swims nor sinks; instead, it relies on the tension.

I think about this a lot lately.

The Membrane at the Edge

Water is a polar molecule. One end carries a slight negative charge, the other a slight positive charge — and because of that, water molecules are constantly reaching toward each other, hydrogen bond to hydrogen bond, in a kind of molecular handshake that never fully lets go. At the surface, where water meets air, something remarkable happens: the molecules on the edge have no partners above them. So they pull inward and toward each other with even more force. That inward pull is what we call surface tension. It’s not rigidity. It’s cohesion under pressure.

The surface is the most energetically active place in the system. It’s where the holding happens. And it’s where, if you know how to work with it rather than against it, extraordinary things can move.

Growth doesn’t happen despite the tension. It happens along it.

I am not a biologist. I’m a brand strategist and web designer with 2 decades of experience and a recent Pilates instructor certification, and I’m currently navigating how to define what I do now. But when I started understanding surface tension — not as resistance, but as the thing that holds form at a boundary — I recognized exactly what the past year has felt like.

The Friction Has a Name

There’s a specific kind of discomfort that comes with becoming something your industry doesn’t have a clean category for. It’s not quite imposter syndrome, though that is familiar too. It’s more like standing at a threshold, feeling simultaneous pulls from both the familiar and the unfamiliar, the established and the emerging, and not being sure whether you’re about to break through or break down.

With two decades of design experience, I know how to build a brand that sticks. I know how to create coherence from scattered parts. What I’m learning now is that the same principles apply to the person doing the building. You can’t develop coherent visual identity work while running a dysregulated nervous system — any more than you can mix oil and water and call it a solution. Oil isn’t polar. It doesn’t form those bonds. Coherence requires the right molecular conditions.

So I got certified. I started teaching Pilates. I went deeper into my Qigong and Tai Chi practice. And I started noticing that the small business owners I work with — the ones in the middle of a rebrand, a pivot, a reinvention — are experiencing the same thing I am. The friction isn’t a sign that something is wrong. It’s a sign that something is happening.

Surface tension, doing its job.

What Your Nervous System Already Knows

Dr. Stephen Porges spent decades studying the Autonomic Nervous System’s role in safety and connection — work that became Polyvagal Theory. The simplified version: your nervous system is constantly scanning for threat, and when it finds something that looks like danger — including the danger of growth, exposure, or becoming visible in a new way — it responds. Heart rate shifts. Breath shortens. Thinking narrows.

This isn’t dysfunction. This is the system working exactly as designed.

The problem isn’t that your nervous system responds to the edge of growth as a threat. The problem is when we interpret that response as a reason to stop. Or worse, when we push through it so hard and fast that we blow past our capacity to integrate what’s happening.

In Somatic Experiencing — a body-based framework developed by Dr. Peter Levine — there’s a concept called titration: working with difficult material in small, manageable doses. Drop by drop. Borrowed from chemistry, where you slowly introduce one solution to another until equilibrium is reached without flooding the system. The membrane holds, then yields, then holds again. Just like water on a surface.

The most direct tool I’ve found for staying in that zone is movement.

The Tools I Use

Pilates teaches you to find your center before you load it. You don’t ask the spine to bear weight before establishing what supports it. Qigong teaches you to sense the quality of your own energy, not to perform calmly, but to genuinely return to it. Both practices build what neuroscientists call vagal tone: the resilience of the vagus nerve, which governs how fluidly your nervous system moves between activation and rest.

High vagal tone doesn’t mean you’re never activated. It means you can come back. The membrane flexes without breaking.

There’s one more tool I didn’t expect to mention in a post about biology and nervous systems: AI — specifically, Claude. Not as a shortcut. Not as a ghostwriter. But as a cognitive offloading tool for when the mental load of becoming something new gets heavy enough to push me out of my window of tolerance.

When I’m mid-transition — in my own work or a client’s — the language to generate, frameworks to hold, and decisions to track can be enormous. Using AI to think out loud and hold structure while I do the actual transformational work functions exactly the way a Pilates reformer does. It’s not doing the movement for me. It’s providing enough external support that my system can go deeper than it could on its own.

The water strider doesn’t fight the surface film. It uses it.
