excellent book. Written by an academic who understands the limitations of academic knowlege in application to trading. Routinely pisses off the "real" academics at major institutions by telling them they are full of crap.
The main thrust of the book is that some superstars in many walks of life are really just lucky while the true talent avoids the limelight and quietly kicks ass consistently. He also explains "survivorship bias" which clouds our perceptions of who is talented and who isn't.
One caveat; you should have some understanding of probability and statistics first, otherwise you could get lost and miss the main points of the book.
