Interesting that we all have read the same books.
Think and Grow Rich (a lot of universal principles not only in the finances or business)
Rich Dad Poor Dad (The Author was bankrupt many times using his techniques. However, he found his website and shared some of the good examples on how to start shifting your mind on finances)
The Richest Man in Babylon (A few stories depicting the characteristics of a human being, from merchant to lender, to a land owner. Also how to deal with finances, some good analogies)
There are many more books, that's for sure. Keep in mind that someday you will have to apply the knowledge, or else knowledge without action is an empty gun. x)
