Do you wanna know what the biggest problem with writing a business novel is?
It's that I have to tame down the real life stories I've collected (some are mine, many are other peoples) so that they don't sound like I've made them up. Last week I had a nice lunch with a very clever friend who told me all sorts of stories ... none of which are remotely believable in fiction. This evening my wife told me something that I can't even put on my blog (it involves lots of wasted tax payers money) because you'd say "he's just made that up".
Real life is a whole lot crazier than fiction.
