When it comes to prosperity and abundance, I gladly recommend material by Randy Gage. Since you already know that this is something you intend to focus your mind upon and want more information, I recommend
the 5-book prosperity series. They come as cheap as $20 as e-books and $30 as paperbacks (all combined). If you want further info about them, have a read through the reviews of these books I'm currently writing on my blog.
