Number Four: Cleaning

Washing up!
The beauty of this is that you can let it mount up whilst you're "busy" working towards that deadline. The critical point - running out of cutlery (even if it's just a fork for a hurriedly made pot noodle), realising that you can't reuse your coffee mug AGAIN without contracting some horrid stomach bug or the remnants of the last 72 coffee dregs sliding down your gullet, or finding an infestation of mice a la Withnail and I - will always come the night before your hand in when you're desperately trying to make up for all the time you've wasted on work avoidance tactics numbers one, two and three (so far). But then, it really has to be done. Your mother would be so proud.
