Investor's Quotient: The Psychology of Successful Investing in Commodities and Stocks - Jaco... Book

The first few chapters were incredibly helpful, and then it got increasingly complex. I suppose the idea is that you'll read the first chapters (on investing smaller amounts of money), then move on to the next chapters after you're already practiced in those means of investing. I tried to read it straight through, and stopped understanding what was going on after a while.

If you understand finance jargon, you'll probably do better with it than I did. If you're a beginner, maybe you should find another book.
