According to Cliff Arnalls, a part-time tutor at Cardiff University, the 24 th of January was the most depressing day of the year . He even came up with a formula forecasting this day of misery which included elements like 'foul weather', 'debt', 'lack of money' and 'days since Christmas'. While it may have been a dark and dreary day for some, for me it was well and truly spring. Like many in marketing-related roles, my job requires me to always think a few months ahead.
