Number one would be by far producing & directing films (or a good television series) one day.
I'd like to meet:
I'm waiting for my future self to show up and tell me everything I'm doing wrong.
Oh well, so much for that.
Music:
There are so many... I used to have them all listed but it was getting ridiculously long. A few favorites are Depeche Mode, Fad Gadget, Talking Heads, The The, Roxy Music, T Rex, A Certain Ratio, The Durutti Column, David Bowie, Joy Division, New Order, Franz Ferdinand, Tear Garden, Ultravox, Cabaret Voltaire, Public Image Ltd, most post-punk acts and a bit of glam when I'm in the right mood.
