For the writer, as I've noted before, nothing is wasted.
I spent the best part of two years editing documents for a coal-mining company. As it happens, the opportunity has arisen to write a coal-mining story (or, more accurately, a story in which coal mining plays a big part). I've been checking various things in the story with a miner buddy, and he verifies that the plot points I need are plausible. It was quite exciting to find out I can have a bit of faith in my own ability to learn and figure things out, and then to take that next leap and make a story out of them. Yee-hah!
On unrelated matters, the third season of Doctor Who just premiered in Australia, and I can only say Martha Jones so, so ROCKS!!!; and I have a nasty head cold. Can't win 'em all.
