This guy mentioned a lot about the book "Think and Grow Rich," so I thought maybe it is an excellent book and then looked it up. Surprisingly, I found out that it is in the public domain now, which I believe means that we can download and read its ebook version completely legally. Thus, I found a PDF version of this book, and I'd like to share with you guys.
Here is the webpage where I found this:
Here's the link that is directly linked to the ebook: http://s3.amazonaws.com/Worksheets_and_Shownotes/OTHER%20GUIDES/ThinkandGrowRichebook.pdf
Hope you guys enjoy this!
