There is a British radio program called Desert Island Discs that has been running for decades. Imagine you are marooned on a desert island with only a record player and eight single records. (I did warn you it's an old program.) What are your records, and what parts of your life do they represent?
You are also allowed one book, but not the Bible or Shakespeare. And one luxury: nothing like a fishing line that would be any real use to you.
I've got my own personal list of tracks for when I'm famous but the book is more elusive. Just one book that might have to last you the rest of your life. Mind you, if I had to live off the land on a desert island the rest of my life might not be very long.
I've often thought I'd choose Witches Abroad by Terry Pratchett as my one book because it covers so many fairy tales and because it's funny and I'd need a laugh if I was to survive. It's an old favourite, so maybe I'll stick with it but I'll miss some of my other old favourites (see Herding Cats below).
I'm not sure how I'd survive without a fresh supply of books. If I had pen and paper as my luxury I could write my own but that wouldn't give me what you'd call a steady supply.
