In November 2011 I travelled to Amsterdam for the Quantified Self Europe conference. It was my first ever unconference, and I was nervous enough about it that I started my website while I was there — the first two posts on riggare.se were written during those two days.
Reading them today is a bit like finding an old photograph of yourself: “I love the idea of having the focus of the meeting on the breaks between the presentations, since everybody knows that the really sparking ideas are born over a cup of coffee and some strange looking local speciality…”
I had no idea how right I was.
What I brought with me
My show&tell was called “Monitoring Parkinson’s“. I talked about using an iPhone reminder app to get my medications taken on time — six different drugs, six times a day, in six different combinations — and how the app eventually made itself unnecessary, because I had learnt to feel in my body when the next dose was due. I talked about jumping onto a Nintendo Wii balance board in the mornings, and about tracking my sleep.
And I ended by saying that what I really wanted was to learn more, that what you call a person who wants to know as much as possible about a subject is a researcher, and that I wanted to be one. A few months later I started my PhD at Karolinska Institutet.
I had been doing versions of this for years — noticing, noting, testing, adjusting — without having a word for it. The first time I heard the expression Quantified Self, I felt seen. There was a name for it.
What I found
Somewhere on the first day I sat through an ignite talk about tracking the effects of alcohol by Caspar, a blue-haired child psychologist with his arms full of the most wonderful tattoos: a bright yellow rubber duck, a billiard 8-ball, a stick of lipstick and many many more. I was sitting in the middle of a row and my first thought was a very Parkinson’s thought: that I couldn’t leave without drawing attention to myself. So I stayed. And while I was sitting there, not leaving, it occurred to me that what Caspar was describing could be used to help people with Parkinson’s.
At the next QS Europe conference, he and I gave a joint talk about where that idea had gone in the meantime — via an app, a national health service competition and a clinical trial. Our advice to the audience was: don’t assume you know where your idea will go, and make good use of the breaks.
But the thing that actually kept me coming back took me three conferences to be able to put into words. I tried to explain it to my husband after the third one, thought about it for a while, and then realized:
> At Quantified Self, I forget I have Parkinson’s.
Because at QS, nobody evaluates or assesses you. Nobody looks at you and wonders what Hoehn & Yahr stage you are, or what your UPDRS score might be. Everybody there is measuring something about themselves, and they respect your efforts to improve your own life without judging them. If you have spent enough of your life being a set of scores in someone else’s notes, you will understand why that is such an empowering feeling.
That is what I mean by finding my people.
What I got wrong
When I stood up in Amsterdam in 2011, I thought Quantified Self was about the technology. The gadgets. I was optimistic — we probably all were — that the emerging sensors and apps were going to let us manage our diseases in ways we couldn’t yet imagine.
I was wrong about that. Technology matters, but as a tool, not as the goal. The goal is to use your own data to answer your own questions. And getting there is hard: hard to ask the right question, hard to find a tool accurate enough to trust and open enough to let you explore your own question rather than the manufacturer’s, and hard to find the time.
That last one tends to get left out. I see my neurologist for about an hour a year. The rest of the year is already full of organising pills, restocking pills, exercising, and, ideally, having a life. In 2015 I suggested we start talking about “the burden of tracking”, alongside the burden of disease and the burden of treatment. Self-tracking has to be worth the effort — and most of the time, for me, it isn’t. So I track when I have a reason: a new symptom to investigate, a dose to time better. Then I stop.
That is not a very good sales pitch for self-tracking. It is, I think, an honest one.
Why a book?
There is a persistent misunderstanding about our community: that we sit around swapping data. We don’t. What we share is methods — how someone framed their question, what they chose to observe, how they reasoned about what came back, what they did differently afterwards. In personal science it is the methods that are generalisable, not the results.
Methods can be written down. That is what the book is.
The Quantified Self comes out on 6 October, written by Gary Wolf with co-authors Thomas Blomseth Christiansen, Martijn de Groot, Steven Jonas, Jakob Eg Larsen, and myself. It has two jobs: to set out self-research methods clearly enough that a beginner can get started and an experienced self-tracker can sharpen their technique, and to make the case that this work is worth taking seriously. Self-tracking is not a hobby for the worried well. Reasoning carefully about your own life using your own observations is part of the basic human toolkit — and for those of us managing a complex condition in the hours when nobody is watching, it isn’t optional.
Apparently pre-orders matter a great deal to whether a book survives its first weeks — more than I understood before I was part of one. So if you think you will want a copy, ordering now genuinely helps:
- If you’re in the US:
- Pre-order on Amazon: https://www.amazon.com/dp/1523527927
- If you’re in Sweden, you can preorder via:

Fourteen years ago I went to Amsterdam to find out whether anyone else was doing what I was doing. I found my people. Now we have written it all down.
