For the last few years I’ve scratched a meager living as a travel writer. If that conjures images of five-star luxury and all expenses paid cruises around the Baltic, then I apologize. The reality was more like a cut-price buffet at a roach-infested diner, squatting in the ass-end of nowhere. While there have been perks – lots of travel, a few unexpected adventures, some truly global friendships – there were plenty of bad times too. It turns out that travel writers dress like bums for a reason. Those guys you see scrawling on scraps of card at the side of the road aren’t begging for small change – they’re on assignment for National Geographic.
