This is a great place to start. Robert Kiyosaki has an amazing ability to lay out principles in a simple and fun narrative. This is a super simple and fast read. I would recommend starting with the audiobook.
This is the best sequel to Rich Dad, Poor Dad. If you loved Rich Dad, Poor Dad and you are ready to move on, this book is your next step. This book is more visual and I would recommend the paper book.
This is one of the all time classics. It was published in 1937 and has a writing style that is a bit old fashioned. If you liked the movie “The Secret,” this book was the inspiration. You might want to start with the audiobook version and then pick up a paper copy to really study it. However, you will want to study it. My copy is filled with underlines, highlighting and notes in the margins.
