It was midnight. I was surrounded by volumes of research, laptop open, deadline looming. And the doubt arrived …. loud, unwelcome, presenting itself as truth.
I can't do this.
I had said yes to writing a book in six weeks. Signed on the dotted line and sealed my own fate. I had wanted this moment for many years, it was a dream come true. And yet, there I sat, in the dark, with doubt loud as hell — not a whisper but a shout, taunting me with the certainty that I couldn't do this. That I'd got it wrong. Panic set in that it was high time to stop, but the deadline told me I must press on. I wanted this so badly, but the words just wouldn’t flow.
The doubt wasn't subtle. And for a little while, I believed it.

What was subtle — what I had to really strain to hear beneath all that internal, negative noise — was the other thing. A tiny, steady murmur. A quiet refusal to fully believe the doubt. A small, almost shy voice saying: but what if I can? What if this was EXACTLY what I needed to be doing. What if every twist and turn before this had led me precisely to typing the very next word on the page?
Here's what nobody tells you about pursuing big goals, taking on chosen challenges: the fear arrives loudly. The belief arrives quietly. And everything that follows - navigating the twists and turns of the entire experience, and ultimately, the outcome itself - depends on which one you decide to listen to.
What I've started calling the Stretch Season
I want to give a name to a particular way of working — one that isn't burnout, isn't hustle culture, and isn't reckless self-depletion. It's something entirely different.
A Stretch Season is a period of chosen, intense effort toward something you've never done before. You put yourself there deliberately. You've decided this is worth doing. You've never done it, so you can't know for certain whether you can — and that's exactly the point. You're going to give it your all, and you won't come out the other side the same person who walked in.
This is distinct from being overwhelmed by an impossible workload. It's distinct from chasing someone else's definition of success. A Stretch Season is voluntary. It belongs to you. You’ve built yourself up to this point, got yourself here. This is intensity is by design.
And yet — as I sat at that desk at midnight — it didn't feel voluntary. It felt like survival.
What the science says about chosen difficulty
There's a body of research on what psychologists call voluntary challenge — the deliberate pursuit of goals that sit at the edge of our current capability. It turns out this edge is a very specific, productive place to live.
Neuroscientist and learning researcher Andrew Huberman has written about what happens in the brain when we engage with genuine challenge: dopamine isn't released at the achievement of a goal, but in anticipation of it — and critically, in the sustained effort required to pursue it. We are, at a neurobiological level, built for effortful pursuit. Not comfort. Not ease. The satisfaction we feel after hard work isn't incidental — it's the whole point.
Psychologist Carol Dweck's research on growth mindset offers a related frame: the brain literally grows new neural connections when we push through difficulty. The discomfort of not-yet-knowing, of being stretched, is the mechanism of growth itself — not a sign that something is wrong.
And then there is this, from the field of positive psychology: researchers Mihaly Csikszentmihalyi and colleagues found that some of people's most meaningful and memorable life experiences occur not in relaxation, but in flow — that state of absorbed, effortful engagement with a task that is just difficult enough to require everything you have.
The midnight doubt wasn't evidence I'd made a mistake. It was evidence I was somewhere genuinely new. Terrifying? Yes. Exhilarating? Also yes.
The thing you can only find there
I've been thinking about something that endurance athlete Kelsey Pfendler said recently when asked why she subjects herself to relentless physical challenge.
"There's a piece of me I don't really get to hang out with unless I'm doing really hard things."
I read that and felt something recognise itself. In that moment, I realised I have this exact experience with my stretch season projects. Which is ultimately, why I say yes despite the fear.
There is a version of you that only shows up under a certain kind of pressure. Not the pressure of impossible demand, not someone else's urgency — but the particular, chosen pressure of I said I would do this and I don't know if I can. I guess I’m going to find out.
When I sat at that desk at midnight, hands shaking a little, wondering if I was completely out of my depth, something else was also happening. I was finding out who I was when I was afraid and kept going anyway. I was becoming someone I hadn't been before — not because the book would be finished, but because I was in the messy middle of showing up, finding my way forward and choosing to finish it.
This is what a Stretch Season gives you that nothing else does. The comfort zones, the familiar paths, the tasks you've done before — they confirm you. A Stretch Season creates you.
You walk in not knowing if you can. You stay when every signal says leave. And you come out the other side as someone new.
The anatomy of a Stretch Season
If you're in one right now — or considering entering one — here is what I've come to understand about how they work.
1. You chose it, which means you can trust it. The doubt that arrives in a Stretch Season feels identical to the signal that tells you to abandon a bad idea. It isn't. The difference is that you chose this. You said yes to it with your whole self. When the noise gets loud, return to that original yes. You made the decision in a clear moment. Trust past-you, before fear had any sort of grip.
2. The discomfort is load-bearing. If it were easy, it wouldn't be stretching you. The difficulty is not a design flaw — it is the mechanism. Every moment you stay when you want to leave is literally building new neural architecture. The discomfort is doing the work.
3. The belief is quieter than the doubt — that's not a problem. The doubt will be loud. It will present itself as fact. Underneath it, the belief in your ability to grow to meet this moment is smaller, steadier, less dramatic. That's not a sign the belief is wrong. It's just how these two things work. The doubt shouts. The belief murmurs. You have to lean toward the quiet, unshakeable one.
4. The person who comes out is not who went in. This is the part that is hardest to believe in advance and impossible to doubt afterwards. A Stretch Season does not just produce an outcome. It produces a new version of you — one who has done a hard thing and knows it. You carry that with you. It becomes part of what you believe you're capable of. I have lived this many times over and have many more stretch seasons to come.
5. It ends. This is not your permanent operating mode. A Stretch Season is a season — bounded, chosen, specific. It has an exit, a finishing line. You will not live here forever, and you're not supposed to. What you're supposed to do is come through it and bring back everything you found.
The question worth sitting with
When I closed the laptop that night — not to escape but to sleep, to let my exhausted brain consolidate what I'd done — I understood something I couldn't have known before I started.
The version of me who wanted to write a book for many, many years had not yet met the version of me who would actually write one. Those are two different people. The Stretch Season was the passage between them. The intense birth of me as an author. After that, I stepped into more Stretch Seasons and with each one, a new part of me was unlocked, revealed, integrated into reality.
You don't have to wait until you're certain you can do it. Certainty is not how you get to a new version of yourself. You get there by choosing something that requires more than you currently have — and finding out that you can is all part of the quest.
Have you ever transitioned through a Stretch Season? Who did you meet on the other side?
