I originally welcomed the mobile phone as it seemed to me that it would enable you to work from anywhere. On the mobile, who was to know if you were sitting on the branch of a tree or sitting in an office? But it instead had the opposite effect: instead of freeing us from the office, it allowed the office to take away our freedom.

Working is bad enough in the winter, but in the summer it can become completely intolerable. Stuck in airless offices, every fibre of our being seems to cry out for freedom. We're reminded of being stuck in double maths while the birds sing outside.

Our dreams take us into other worlds, alternative realities that help us make sense of day-to-day realities.

Life is becoming no more than staring at the screen.

When you go for a walk, take seeds with you, poppies, rainbow chard, rocket. Plant them among the weeds in patches of wasteland. See what happens.

In a world where you are constantly asked to be 'committed,' it is liberating to give yourself the license to be a dilettante. Commit to nothing. Try everything.

It takes a while to master the art of hammock-lounging. At first I could only manage five minutes or so before I thought I ought to get out and go and help a child learn how to swim or something. But after observing the Mexicans' capability for staring into space for hours on end, I decided to put in some proper practice.
