High quality blogs
Very insightfull stuff, although I don't find too many them... but if you can find one, go ahead and read it, definitely worth it.

Save your money
I'm sorry that I bought this book. The grammar is terrible, and the author (or his editor) doesn't even know the difference between principal and principle. The author cannot settle on one word or phrase for a concept, but generally, and repeatedly uses three. Save your money.
