The question shouldn't be what we ought to do, but what we can do.

I left things out - my motivations, my history, my emotional responses - because I am not good at understanding them or writing about them. I tried and it was generally boring and always unconvincing. Most importantly I wanted to try to place Afghans and Afghanistan in the foreground rather than my own character.

I do a lot of work with policymakers, but how much effect am I having? It’s like they’re coming in and saying to you, ‘I’m going to drive my car off a cliff. Should I or should I not wear a seatbelt?’ And you say, ‘I don’t think you should drive your car off the cliff.’ And they say, ‘No, no, that bit’s already been decided—the question is whether to wear a seatbelt.’ And you say, ‘Well, you might as well wear a seatbelt.’ And then they say, ‘We’ve consulted with policy expert Rory Stewart and he says . . . .’

The Afghan government is much better informed, much more intrusive and ambitious than I had guessed. There are amazing craftsmen in Kabul but few designers and wage rates are astonishingly high - which is a problem when trying to support and promote Afghan craft exports. The community in Murad Khani in the old city - who we are helping to restore their area - have been the best part so far - eccentric, led by a champion wrestler, determined, proud and courageous.

Despite the dubious statistics … democracy is a thing of value for which we should be fighting.

The point about democracy is not that it delivers legitimate, effective, prosperous rule of law. It's not that it guarantees peace with itself or with its neighbors. ... Democracy matters because it reflects an idea of equality.

I found incredible kindness, dignity and hospitality in both Iraq and Afghanistan - am only alive because of it - the most worthwhile lesson of a twenty month walk to these countries was a deepening appreciation of the kindness of strangers.
