The mug had gone cold again before I noticed I was holding it. Six months ago that would have meant something - a small failure, evidence I couldn't even manage a cup of tea without my mind dragging me somewhere else. Now it just meant the tea was cold. I tipped it out, refilled the kettle, and stood at the window while it boiled. That, more or less, is the honest measure of what six months of sitting still for ten minutes each morning has done. It hasn't made me a calmer person in any way I could put on a certificate. It has made the cold tea smaller.

I want to be careful here, because there is a tidy story I could tell you and it would be a lie. The tidy story says I was frayed and now I am whole, that I sat down each morning and watched my old self dissolve. People love that arc. I loved it too, which is part of why I keep having to resist it. The truer thing is duller and, I think, more useful: almost nothing dramatic happened, and a few very specific things changed so quietly I only noticed them in hindsight.

You probably know the kind of change I'm not describing. The overnight one. The before-and-after photo of a life.

Here is what actually shifted. There's a gap now, before I respond to things. Not a long one - half a second, maybe a full one on a good day. My partner says something that lands wrong, and where I used to be already mid-sentence with my defence, there is now a small pause I didn't put there on purpose. Sometimes I still say the sharp thing. The gap doesn't stop me. But I can feel it, the way you feel a stair you didn't expect, and often that's enough to choose differently. Six months ago that gap did not exist. I went from stimulus to reaction with nothing in between, like a hand pulling back from a stove.

I noticed it first in traffic, of all the unromantic places. Someone cut across me on the way to the shops, the old hot flush started up my neck - and then it sort of arrived at a closed door. The reaction came, I watched it come, and it didn't have anywhere to go. I didn't feel serene. I felt mildly surprised, the way you'd feel finding a room in your house you'd forgotten about. That's the texture of it. Not peace descending. Just a bit more room than there used to be.

The other change is harder to name. I notice more. Not in a heightened, every-leaf-is-a-miracle way - I'm suspicious of people who talk like that, and I'm not one of them. It's smaller. I notice when I'm bracing. I'll be reading an email and realise my shoulders have climbed up towards my ears, and now I clock it, where before it would just have been my Tuesday. Knowing doesn't always fix it. Plenty of mornings I sit for my ten minutes and spend the whole time making a mental list of things I'm behind on, and I get up no stiller than I sat down. But even on those mornings, the noticing has sharpened. I can tell you what my anxiety feels like in my body now. I couldn't have, before. It was just weather.

So let me be plain about what it did not do, because the brochure version skips this part.

It did not make me less ambitious, or make me stop minding about my work, or turn me into someone who floats above her own life. I still get short with people I love. I still lie awake some nights running the same useless loop. The practice didn't cure my temper or my impatience or the particular way I have of catastrophising at three in the morning. What I found is not a different self. It's the same self, with a slightly longer fuse and a bit more honesty about which fuse is lit. That's smaller than I was promised, by myself, six months ago. It's also held up, which the bigger promises never did.

If anything surprised me, it's that the ten minutes themselves are almost never good. I think I imagined I'd grow into them - that by month six I'd be sitting in some clear pool of attention. I'm not. Most mornings are restless and ordinary and faintly boring. The change didn't happen in the stillness. It happened in the rest of the day, downstream, in the half-second gaps and the noticed shoulders, as if those ten unremarkable minutes were quietly recalibrating something I couldn't see and never got to witness directly.

So if you've been sitting for a while and waiting for the transformation to announce itself, I'd gently offer this instead: stop looking at the practice and look at the cold tea. Look at the half-second before you snapped, or didn't. Look at the moment in the queue when you caught your own jaw clenching. That's where it lives, if it lives anywhere. Not in how the sitting feels, but in the small undramatic places it leaks into afterwards, the ones too ordinary to count as a story.

I went back to that cold mug this morning and almost laughed. Six months of work, and the headline result is that I throw out less tea than I used to. But I'd take this - the slightly longer pause, the shoulders I can feel climbing, the unspectacular, durable, hard-to-photograph version of change - over the bright clean transformation I was hoping for. It asks less of me to keep. And the kettle is still warm, and the morning is still here, and that, it turns out, was always going to be enough.
