The book "Leaders Eat Last" by Simon Sinek might be a good book to read. I haven't read it yet, but based off of the reviews it has received, it just might be good to read it and see what it has to say.
"7 Habits of Highly Effective People" is also a really good book about leadership and business in general. There are no get rich quick tips in there, but it is a way to train your mind and they way you present yourself for success. I also like the ".....for Dummies" books as they tend to make things simple and easy to understand and yet provide some good sound advice.
I think that one book that really made me think about life and business in a whole new way has to be the Millionaire Fastlane by Mj Demarco. That book is one of the best books that I have read on the topic of businesses.
I just ordered "The Master Key System" by Charles Haanel on Ebay a few days ago, so I'm hoping it will arrive somewhere next week. It's my first book I ever ordered about this topic, so I'm very excited about it. I've heard some good stories about this book. Oh, and I know there is a free pdf available, but I really hate reading from a screen, so thats why
"The Millionaire Next Door" and "The Millionaire Mind" were very good. "The Ten Roads to Riches" by Ken Fisher is excellent. The "Rich Dad / Poor Dad" series by Robert Kiyosaki have some very good info, but you definitely want to be careful when it comes to borrowing / flipping / leveraging, etc.
"The Master Key System" is definitely something to check out. These are all great suggestions. I've read and heard of a few but not all of them. This definitely gives me something to look into the next time I go to the store.
Napoleon Rich - Think and grow rich, although I'd suggest you to develop your business mind naturally, not by others' own experiences.
The Lean Startup by Eric Ries. It's a great business book that you can get which was published pretty recently, in 2011. It's a good up-to-date starting book that will give you all you need to know to get into the field. It is definitely effective and will get you rolling into money after reading it. It's a good buy, you should get it!
