Walking around becomes actually difficult. But the walking process is the oldest natural form of movement. It puts you literally in touch with the earth and the weather around you and allows you to get into conversation with people as you move, which seldom happens in the other ways we move.

London is a city that sleeps too much. This is the mould of its quality. A magnetic contract: to reinvent itself on the other side of dream, each day. And such dreams, smouldering against the tidal spine of the river, telling and retelling the tales that must be told to manifest a city's bones. Whispering the night architecture back into stone.

As you withdraw energy from the city, you are also giving energy back. People are noticing you. You're doing something, you're there, the species around you absorb your presence into it, and you become part of this animate entity called the city.

Life and career are the same thing. Every life has to have a plot and a plan. You have to recognize this early and be quite cold-blooded in the discovery and articulation of that plot.

You'd better make it your business to understand the market. The ability to charm or play the game is useful.

Culture isn't all just about what can be tweaked and twitched in the simplest possible way. As people move around, they literally don't see what's around them, because they're wedded to earworms that are burrowing into their heads endlessly in a kind of negotiation with these tiny screens.

The line of traffic advancing towards the rising sun looked like a procession of the returning dead. Every one of them, solitaries in clean shirts, smoking, checking mirrors to see if their reflections were still there, wore dark glasses.

An involuntary return to the point of departure is, without doubt, the most disturbing of all journeys.

I got interested in the contradiction between people who are understanding the city by not moving a single inch, by remaining in the same place all the time, and people like me who are constantly roaming around.
