I also like other books by Napoleon Hill and this particular one is not the best as for me, but surely Think and Grow Rich will be helpful for any entrepreneur

It is definitely essential book - reading Think and Grow Rich by Napoleon Hill really pays back.

Think and Grow Rich PDF or a ebook is a good variant for a student. Personally I bought hardcover, but a friend of mine also purchased a kindle version (and was pretty happy with it). Napoleon Hill is a great writer!
