I haven't kept a diary for a few years now, though this thread has inspired me to do so again. It is important to remember what occurs in your everyday life, for though it may appear mundane at first, it can come in quite handy, and be a good read, in the future... The last time I tried to keep a diary was on a trip to New Zealand last year, but I failed hopelessly after the fourth day. Fortunately though my memory (and family!) served me well and I ended up writing up a long, comical take on our adventures through the South and North islands.
