I am the master. It's something in my life I can honestly say I'm good at. I wrote a certain document a few days ago and Word tells me I spent around 500 minutes on it. It was 405 words long. I win!
My best essay-writing, Remixor-style, came when I had to write an essay of 2000 words or so for the next morning. Me being me, I decided to sod that and went off to the pub. When I woke up the next morning, I realised what I'd done and immediately leapt on the computer to get typing - only to find a finished essay waiting for me. It needed a bit (well, a lot) of editing, but there it was - when I came to think of it, I vaguely remembered sitting up half the night bashing it out, but I was surprised that the end result was so comprehensible.
