If you took away all pain, if everyone lived forever, everything would be bland, flat and boring; there would be no reason for art, music, newspapers, love because we would all be in a mono state of happiness.
Teenagers are in some ways the best readers because their imaginations haven't been narrowed down by boring things like jobs and the realities of money and capitalism.
It would be lovely to live in a culture where calmness was the aim.
I think we get too hung up on categories. Obviously, the book market has to categorise things, and it makes it easier for a reader to go into a bookshop and choose, but as a writer, it helps to get rid of all of that and imagine you are a storyteller around a campfire.
Robots are great. I am saying that now so that when a future civilization of robots takes us captive, they will search through the 'Guardian' web archive and realise I said, 'Robots are great,' and then they'll choose to save me.
You are no less or more of a man or a woman or a human for having depression than you would be for having cancer or cardiovascular disease or a car accident.
Human brains - in terms of cognition and emotion and consciousness - are essentially the same as they were at the time of Shakespeare or Jesus or Cleopatra or the Stone Age. They are not evolving with the pace of change.
Books are our umbilical cord to life. They connect us deeply, and with more meaning, to the world. They aren't about escaping from ourselves but expanding ourselves and finding within us the tools we need to survive.
Creative writing lessons can be very useful, just like music lessons can be useful. To say, as Hanif Kureishi did, that 99.9% of students are talentless is cruel and wrong. I believe that certain writers like to believe they arrived into the world with special, unteachable powers because it is good for the ego.
To say that creative writing courses are all useless is almost as silly as saying all editors are useless. Writers of all levels can benefit from other instructive voices.
I think it is a luxury and privilege to be sane and well and pessimistic. Because with depression, you have no other option. You don't want that pessimism, because it is crushing you and keeping you down at the bottom of the well.
Words are the essence of culture. Books are pure essence. They are not for women or for men, but for all of us. Without books, civilisation falls into the dark ages.
My early novels were written in quite a dark place. I stand by them, but I would never write them again. I think it is subversive to embrace emotional optimism, because it goes against the grain.
My mum always said I devoured 'The Lion, The Witch And The Wardrobe' at the tender age of four, but frankly, I think that might be a touch of maternal exaggeration.
However much in the foreground depression feels, you are separate to it. This is going to sound cheesy, but I'd say you are the sky. A cloud comes and dominates the sky. But the sky is still the sky. Depression tells you everything is going to get worse, but that's a symptom. Don't give depression power - constantly discredit it.
I'm a firm believer in the connection between the body and the mind: feed one, feed both. I like to run, but only short distances, and fast. I'm no good at long distance. More than six miles, and the knees start to go.
I suppose the book I really remember loving as a child was one called 'The Outsiders' by S.E. Hinton, about a gang of kids from the wrong side of the tracks in Sixties Oklahoma. I grew up in the Eighties in Nottinghamshire, but this tale of troubled, but essentially good, kids - or 'greasers' - was something I completely connected with.
Depressives have led countries, won wars, flown rockets to the moon, made great music. Don't let depression stop you employing someone, and never let it cause you to judge them. Depression is not a person. Like any other illness, it is something that happens to a person. It shouldn't define them.
There is certainly no one 'type' of writer who deliberately draws on Shakespeare. In fact, there's a strong argument that everyone writing in the English language is influenced by Shakespeare because, to a considerable degree, he shaped that language.
In an age of never-ending health fads, it's comforting to learn that one of the healthiest activities you can do has existed for millennia. It's called reading. Yes, books are not just entertaining or educational: they can also improve your mental health.
