"The Art of Possibilities" (or "Possibility) by a couple named Zander... and it's one of those books that you're glad you picked up at this very moment in you life. It's all about attitude adjustment... and it's not like any self-help books I've seen before.
I actually dig what they're saying.
I think I may purchase a copy for myself, so I can read it a few hundred more times and REALLY *get* it.
If you're into music, creativity, passionate life, or marketing (!) this is a great book. Published by the Harvard School of Business press.
