When walking you see things that you miss in a motor car or on the train. You give your mind space to ponder.

We have an idea that if something we're doing isn't actually earning money, or spending it, then it's completely worthless. But if you start to work less, you can actually start to give more to society, but on a local level.

Facebook is not ideologically neutral. In fact, it emerges from a very particular world view which we can trace back to Hobbes. I discovered this by examining the profile of Zuckerberg's fellow board members who, unlike him, are a very interesting bunch and, I suspect, the real power behind the poster boy.

The world's richest half billion people - that's about seven per cent of the global population - are responsible for fifty per cent of the world's emissions.

Faffing of course does not fit the programme. We are supposed to be busy, productive citizens.

I would like to propose slow cycling. Commute by bike. At a stroke, you remove the need for and absurd cost of public transport. Cycling is almost completely free. There is no longer any need for the gym as you get fit by cycling. And you can go at your own pace.

I like the idea of becoming [fairly] good at lots of things rather than very good at just one thing. So it would be nice to be okay at the guitar or at the piano, a reasonable cook, perhaps able to fix your car or do some basic carpentry, and be able to write the odd article. Rather than being super good at one tiny thing, to be kind of average at lots of things. It might mean that you have a more kind of enjoyable, complete life.
