It's family, and it's faith, and it's friends. I would tell them that. Don't forget that. In your brilliance, don't turn your back on your friends. Don't think you're entitled to something because you're smarter than the next guy.

It’s all a gift. So be grateful for every day.

Don’t make jokes at the expense of Little Mix. They have an ardent fanbase.

The best way to spend time is to waste it.

I was forced to think very hard about what it meant to be me, what it means to be a person who is only a brain. Pascal's 'thinking reed' really does capture it, because I'm just a bunch of dead muscles thinking.

I don't believe in an afterlife. I don't believe in a single or multiple godhead. I respect people who do, but I don't believe it myself. But there's a big but which enters in here. I am much more conscious than I ever was, for obvious reasons, of what it will mean to people left behind once I'm dead. It won't mean anything for me. But it will mean a lot to them. ... So in one curious way I've come to believe in the afterlife as a place where I still have moral responsibilities, just as I do in this life except that I can only exercise them before I get there. Once I get there, it'll be too late.

So it seems to be my responsibility, particularly to my children, also to my wife and friends, is not to be Pollyanna and pretend everything's okay no one would take me seriously if I said that but it's to be as present in their lives now as I can be so that in years to come, they don't feel either guilty or bad at my having been left out of their lives, that they feel still a very strong not a memory of particular actions but a memory of a complete family rather than a broken one. That seems to be something I can do or try to do.

But if I was sitting in an armchair with bits and pieces of rubber sticking out of me and my son came over and said, you know, would you like a banana? Wink once for yes, wink twice for no, I dont think the interest of the conversation would get me past the sense that this is horrible. It's horrible for me but above all, horrible for them. There are things worse than death.

I see the future as something that could come crashing down very fast. Let me put it slightly by way of a comparison. Normal people, and I use the term very deliberately, by this not otherwise able situation - I'm disabled. I'm abnormal. Normal people dont think very much about the medium term future. They think only about the present, which is constantly changing for them or the very far future, which is just an abstraction. For me, its the other way around, my present never changes. So I dont really think about. But the medium term involves my death so I'm quite conscious of what is going to happen to me in about a year, maybe two years, who knows, whereas no one else I know thinks like that.

This cockroach-like existence is cumulatively intolerable even though on any given night it is perfectly manageable. “Cockroach” is of course an allusion to Kafka’s Metamorphosis, in which the protagonist wakes up one morning to discover that he has been transformed into an insect. The point of the story is as much the responses and incomprehension of his family as it is the account of his own sensations, and it is hard to resist the thought that even the best-meaning and most generously thoughtful friend or relative cannot hope to understand the sense of isolation and imprisonment that this disease imposes upon its victims.
