Today, Monday the fifteenth of January, the third Monday in the year, is, unofficially, the most depressing day of the year. It’s become known as Blue Monday. Christmas and the New Year celebrations are but a distant memory; the decorations are down; the Christmas market has packed up and left. It’s cold and it’s dull and it’s grey. What’s more, we spent all our money on Christmas presents, booze and fireworks, and are now waiting impatiently for our next pay packet. We’ve given up drinking; we’ve given up smoking; we’ve promised ourselves to exercise regularly. Now we’ve realised this is reality. Spring and Easter are the light at the end of a very long tunnel, and winter hasn’t even started properly yet.
