Do you remember that account of the girl who tried couriererring only to end up being ripped off by her company? It is a classic but I can't find it on here,I've used the search etc.....
Ha, I read that before I started too! I think it's actually pretty accurate. Well, maybe not the bit about helmets and gas masks, but certainly the stuff about being fit, fast, confident, tough and unconcerned about appearance. And it gave me a good idea of what to avoid!
