These are not numbered for a reason. All of these books are important for various reasons and none are more important than the others. I am listing ALL the books that have had impact on my financial life. Please do not confuse listing order with preference, I am merely adding titles as I pull them off my Kindle.
Unshakeable - Tony Robbins will blow your mind if you let him, and I suggest you do. This is a great book that has 2 specific chapters of "gold" as far as I am concerned. His two chapters focused on mindset make this book worth the price alone. If you want to get ahead YOU MUST change your thought process.
