Napoleon Hill

Oliver Napoleon Hill was an American self-help author and conman. He is best known for his book Think and Grow Rich (1937), which is among the best-selling self-help books of all time. Hill's works insisted that fervid expectations are essential to improving one's life. Most of his books were promoted as expounding principles to achieve "success".Hill is a controversial figure. Accused of fraud, modern historians also doubt many of his claims, such as that he met Andrew Carnegie and that he was an attorney.
