The power of yes!

I've wanted to read Yes Man for ages and I finally got round to picking it up on the plane back from Gran Canaria.

I like the idea of saying yes to everything, but, judging by the raft of dodgy emails I've been getting recently, I'd be in all kinds of trouble if I stuck to it as rigidly as Danny Wallace.

I'd like to know how true some of it is and how much is artistic licence though.
