If Wikipedia is to be believed, serendipity is one of the ten most difficult English words to translate. Like the German word schadenfreude, it's an intangible yet relatively straightforward concept that nevertheless doesn't have an equivalent word in many languages.
Yet it is still a fairly universal concept, and not one that you would think is an exclusively British occurrence.
Winning the artwork wasn't the only case of it here either. Sure, that was a lucky moment anyway, but so was going to the Barbican in the first place (I had arranged to meet a friend elsewhere), so was spotting Stephen Nelson's work before it was packed away (I'd only managed to see about six of the 50-odd works on display) and so was returning from lunch in time to hear my name called (any later and I would have been stood there for the duration, unaware it had ever come up). The whole afternoon was like one big pile up of coincidences, a domino effect triggered by my own susceptibility to happenstance.
And I think susceptibility is the key to all this. If you don't leave yourself open to these little chance encounters, maybe they will never happen. All of the people in the Barbican foyer for the Free Art Fair (see below) came hoping for a fortuitous moment and, for some of them at least, it came. That hope is what keeps the best photographers going too. Everyone is hoping to snap a chance encounter, that decisive moment which no one else has been privy to. Because Cartier-Bresson wouldn't have been such a great photographer if he had sat at home and waited for the inspiration to come. I've realised that if my own photography is going to work, I've got to take my lens cap off a bit more often and put myself out there.
