Latest Bloggingheads up with Robert Greene, bestselling author of The 48 Laws of Power and most recently The 50th Law ("Fear nothing").
Excellent commentary/summary by Andy McKenzie here.
The most important piece of advice I got from The 50th Law was "always attack before you are ready".
Great quote from Greene about how he writes/researches his books:
"if it takes 40 books to find the idea I'm going to read them" http://bloggingheads.tv/diavlogs/23870?in=18:00&out=18:40.
