The Art of The Idea
This is a great book for anyone who struggles with bringing ideas to fruition or anyone who is dealing with a challenging client or aspect of any project. Everyone who picks it up usually finishes it in one setting, partially because it is amazingly informative and also because it's very concise writing.
It is produced by one of my favorite book companies / stores, powerHouse Books in DUMBO. Next time you're in Brooklyn take a walk over, they have a beautiful store right off Riverfront park.
