The Power of a Decision

One of your most underused inner resources, and how to harness it

I am sure you recognise this moment: You’ve been going back and forth on something. A conversation you haven’t had. A direction you haven’t committed to. A standard you’ve been tolerating. And somewhere in the middle of it all, you realise you’ve been in a holding pattern.  You’ve not been moving forward, not fully letting go – just circling.

What we don’t always recognise is that circling is also a choice. Indecision is a decision. It’s a daily vote to keep things exactly as they are.

What I want to offer you in this article is a different way of thinking about decision-making – not as a moment of pressure or risk, but as one of the most powerful inner resources we have as a human being. One that, when we learn to harness it consciously, can shift things in our lives in ways that feel almost immediate.

A decision is not a preference

Let’s start with what a decision actually is, because most of us are confusing the two.

A preference sounds like: “I’d really love to speak up more in meetings.” Or: “I want to stop letting that situation drag on.” Or: “I know I should have that conversation.”

A preference is something we want. A decision is something we commit to.

A decision is a yes. And every real yes is simultaneously a no to something else.

When you decide to speak up in the meeting, you’re saying no to the version of you that stays quiet and walks out feeling small. When you decide to have the difficult conversation, you’re saying no to silent resentment slowly eroding a relationship. When you decide to set a standard in your work or your life, you’re saying no to tolerating less than what you actually need.

The yes and the no are inseparable. You cannot have one without the other. And that’s precisely what gives a decision its power.

What happens in your nervous system when you truly decide

This is where it gets fascinating, and where the neuroscience backs up what many of us have felt intuitively.

When a decision is half-made, as in when we’re in “maybe” territory, our nervous system stays in a kind of low-grade negotiation. The brain keeps the question open, which means it keeps allocating resources to processing it. This is part of why indecision is so exhausting. It’s not that nothing is happening. It’s that everything is happening simultaneously, with no clear direction to move toward.

Psychologist Roy Baumeister’s research on decision fatigue helps explain this: every unmade decision draws on our mental and emotional reserves. We don’t just feel stuck, we become depleted by the stuckness.

But something shifts when you truly decide.

The nervous system moves from negotiation to alignment. Your attention, which was previously scattered across multiple possible futures, narrows and sharpens toward the one you’ve chosen. Your brain (which is extraordinary at this) begins scanning for what you need to make the decision real. Resources that were always there but invisible suddenly become visible. People, conversations, opportunities, ideas. They don’t magically appear; your filter for noticing them simply changes.

Researcher Peter Gollwitzer calls this the difference between a goal intention and an implementation intention. A goal intention is: “I want to do X.” An implementation intention is: “When Y happens, I will do Z.” The specificity of a decision, that is the moment you move from vague wanting to a clear commitment , dramatically increases your likelihood of follow-through. Not because you try harder, but because your whole system organises itself differently.

Clarity doesn’t always come before a decision. Often, it comes because of one.

A decision is also an identity shift

Here’s something I’ve come to understand both through my own journey and through the work I do with others: a powerful decision is never just about behaviour. It’s about who you’re declaring yourself to be.

When I made the decision – really made it, not just hoped for it – to build a coaching practice that was unapologetically centred on courageous conversations, something changed. Not just in my diary or my marketing. In me. I started showing up to conversations differently. I started preparing differently. The decision reorganised my identity from the inside out.

James Clear talks about this in the context of habits: every action you take is a vote for the type of person you wish to become. And I’d take it further: a decision is more than a vote. It’s a declaration.

When you decide (truly decide!) you’re saying: this is who I am becoming. And your nervous system begins stepping into that version of you before you’ve even taken a single visible step.

The freedom we forget we have

Viktor Frankl, writing from his experience as a prisoner in Nazi concentration camps, said something that we can use here:

“Everything can be taken from a man but one thing: the last of the human freedoms – to choose one’s attitude in any given set of circumstances, to choose one’s own way.”

The freedom to decide how we show up is never taken from us. Even in circumstances we didn’t choose, even in conversations we’d rather not have, even in the face of uncertainty, we retain the capacity to decide.

That is not a small thing. It is enormous. And powerful!

And it’s also the thing we most readily give away.  We default to other people’s expectations, to our own fears, to the illusion that we need more certainty before we can commit.

Why we avoid deciding

I want to name this honestly, because I think it matters.

Decisions are powerful. And power is confronting.

Because once you decide, you have to face what the decision requires. You have to move. You have to risk being wrong. You have to tolerate the discomfort of growth rather than the familiar discomfort of staying stuck.

Many of us retreat back into “I’m still thinking about it” not because we lack information, but because the decision asks something of us that feels bigger than we’re ready for.

Brené Brown reminds us that courage is not the absence of fear.  It’s feeling the fear and choosing to act anyway. The same is true of decisions. You don’t wait until you’re certain. You decide, and then you let the decision begin building the certainty you need.

Confidence follows commitment. Not the other way around.

Harnessing decision as an inner resource

You don’t need more motivation. You need a decision.

You don’t need more confidence before you can decide. Confidence is often the by-product of having decided.

You don’t need complete clarity before you commit. A committed direction creates the clarity that circling never will.

When you bring real decision-making to the areas of your life that have been in a holding pattern, something reorganises. Your brain starts looking for solutions instead of rehearsing the problem. Your attention moves from “what if this goes wrong” to “what does this require of me.” Your behaviour begins aligning with the future you’ve chosen rather than the past you’ve been recreating.

Decision is one of the deepest human resources we possess. It’s available to us at any moment. And most of us significantly underuse it.

So let me ask you directly:

What have you been circling around that actually deserves a decision?

What conversation have you been postponing? What standard have you been tolerating? What commitment have you been making in theory but not yet in practice?

What would change (in your body, your relationships, your work) if you stopped considering, and started deciding?

Because here’s what I know to be true:

The moment you decide, you begin becoming.

And that becoming starts now.
