This question is relevant through the whole year I think but specially at Christmas, as I sometimes have a difficult time thinking of what to put on my list. (Yes, I'm spoiled, I know).
I've red Hey Whipple Squeeze This at recommendation of Ivan, and I'm getting myself Freakonomics by Steven D. Levitt and Stephen J. Dubner. I'm also having The Decisive Moment by Henri Cartier-Bresson left to read. What other books would be really useful for this business?
Personally I'd like a book that focusses on the creative process for ads but I'm not sure which one is good. But any recommendation in any field is most welcome.
Thanks in advance!
