Look at it this way. I've a full-time day job. Normally, if I push myself, I can get 1000-1500 usable words a day after getting home. A respectable amount. I've been feeling quite buggered after getting home[0] and yet this week I've still managed to write 9500 usable words. Closer to 10,000 when I add up the straggling fragments. When I've not been doing that I've either been answering the phone or emails (dayjob) or fixing up someone's website (guvvy).
So yeah. Really fucking busy. And knackered.
At least it's holiday time now. No more work until the 7th of January.
