Squaring numbers is a symmetrical process that I like very much. And when I divide one number by another, say, 13 divided by 97, I see a spiral rotating downwards in larger and larger loops that seem to warp and curve. The shapes coalesce into the right number. I never write anything down.
My first memory - at about four - was of numbers. The doctors who study me think a combination of mild autism and seizures I had when I was three have made me experience numbers the way I do.
Someone who copies a Van Gogh does not therefore become Van Gogh, and the same would go for Mozart or anyone else who contributed something that was original. Certainly in the way that I described visualizing numbers in abstract, meaningful shapes.
Our thoughts and our feelings, of course, are not wholly objective, they're inherently subjective. And that's the danger, and I think as long as we're aware of it and can push back against it, I don't think that these two views are necessarily incompatible.
One of the lines from my books is about having respect for different minds, and if I had to have an epitaph at this point in my life, that would be it.
What I do find surprising is that other people do not think in the same way. I find it hard to imagine a world where numbers and words are not how I experience them!
There is this mythology that says that when people are born, their brains are essentially fixed very early on and they're not able to change their connections. I was aware that was a myth and that people could learn new skills.
Retaining a sense of control is really important. I like to do things in my own time, and in my own style, so an office with targets and bureaucracy just wouldn't work.
It was a gradual process, realising I was different. I remember at primary school getting a worksheet with sums printed on it. I thought that they must have run out of the right colour inks and sizes for the numbers, because they were all the same, which isn't how I experienced numbers at all. To me, nine is big and blue.
If when we are taught English we are just taught the rules of grammar, it would take all our love of our language away from us. What makes us love a subject like English is when we learn all these fantastic stories. Feeding the imagination is what makes a subject come alive.
I think if I ever stopped pushing myself, I would revert quickly to quite repetitive, restrictive behaviour. But in pushing myself and concentrating on what I can do, I think I can contribute to society. And that gives me the desire to keep pushing, to see what I'm capable of. The thing to do is not to stop.
I do read a lot, and I think in recent years the ratio between the amount of non-fiction and fiction has tipped quite considerably. I did read fiction as a teenager as well, mostly because I was forced to read fiction, of course, to go through high school.
I certainly have routines in my day-to-day life that are important to me and still give me feelings of security and control, but the capacity to break out of them every so often as I travel has given me a second wind.
37 is a lumpy number, a bit like porridge. Six is very small and dark and cold, and whenever I was little trying to understand what sadness is I would imagine myself inside a number six and having that experience of cold and darkness. Similarly, number four is a shy number.
There are estimated to be fewer that 50 prodigious savants worldwide. If we were brought together, it would be disappointing in the sense of us having different abilities. One thing that would make me feel united with them would be the sense of us having grown up in isolation.
