There's a big, voracious elephant in the room when I encourage writers to live in London: finances. Yes, this is a pricey city that's getting pricier, as people on lower and less stable incomes get pushed further out from the city center.
I don't have the major expenses of either kids or illness, and the UK's beloved National Health Service means that I don't have to fear bankruptcy with every health scare. I'm able to cycle and walk just about everywhere, so I spend almost nothing on transport. And I work a lot, admittedly, including holding down a two-day-a-week office job that pays London wages; employers generally apply a London weighting to salaries in recognition of the high cost of living in the capital.
