I’m increasingly of the view that the only way to lead anything, or anyone, is by example. Oh sure, my heart still flutters involuntarily at the ‘bending the arc of human history towards a brighter future’ type of rhetoric we heard from Barack Obama in 2008, but I’ve been watching him closely ever since and – attempts to overhaul the American healthcare system and stupendous successes at not being George Bush aside – I can’t honestly say I’ve seen a huge amount of arc-bending yet.
