I also wanted to say that I am changing my mind about writing rules and writing advice. Go check out this smart link over at writer Helen Lowe's blog on Ten Bits of Advice Writers Should Stop Giving Aspiring Writers (warning - lots of swearing). I especially like the one on show don't tell (2) and on watching what you say on the internet (4). I've always been one for keeping both show and tell in a story (I find reading all show gives me a headache). As the blogger says - both have their place. I think I want to change my stance on adverbs too. They can be a bit of a lazy option sometimes but sometimes they are the right word for the job.
There is heaps of advice out there and lots of rules and some of it is good but its important to not feel straitjacketed by it all. Advice and rules can be a comfort and sometimes a lifesaver - something to cling on to when the creative seas get rough. But they aren't a cure all or necessarily your saviour. Following them can help make you a better writer and can help you improve your understanding of writing and storytelling, but sometimes you need to ignore the advice and the rules and sometimes you have to break them. They're your friends, not your masters. Don't be their slave.
