This is the best self help book any entrepreneur could ever read. Perhaps the only one they need to. Truly transformative. Napoleon Hill was tasked by Andrew Carnegie to write a book on what made a successful person succeed and he spent 20 years researching and Interviewing great name of the day (Ford, Woolworth, Edison, etc), plus lots of people who failed (because you have to know what doesn't work too). This book is the result. It basically hammers home a single point, over and over again. Success comes from knowing what you want to achieve and having a burning desire to achieve it. The starting point of all achievements is desire. Keep ths constantly in mind. Weak desire brings weak results, just as a small fire makes a small amount of heat.
