I would start with any of the Michael Lewis books. They make the very confusing and complex financial system seem relatively simple and entertaining at the same time.
The Big Short
Liar's Poker
I started following alot of youtube video blogs from economists, journalists, and trader's who talk about markets, interest rates, market manipulation, cover-ups, etc. I'm a slow learner so it took me a good year of reading and watching these guys until all the stuff started to make sense.

I also follow mainstream media, and them look at my sources of media and how they differ. I read lots of articles on Yahoo Finance as well. If you go read some of the articles where they talk about our "Great recovery" or anything economic related and then scroll to the comments section, you'll see how well the population is really feeling. Normally there's tens to 100's of comments bashing the writers for writing.
Most people say diversify is the way to go, but as per jim rogers, diversifying will never make you rich.
