Napoleon Hill was an early life-coach. Born in 1883 in Wise County, Virginia, he first worked as a secretary, a "mountain reporter" for a local newspaper, a manager of a coal mine and a lumber yard. However, his life changed when he got the job as a journalist for Bob Taylor's Magazine where he became the protégé of steel magnate Andrew Carnegie, the richest man of his time and author of How to Win Friends and Influence People. Under Carnegie's guidance, Hill interviewed the greatest industrialists and self-made millionaires of the era to discover the principles that guided them to success. Twenty years of research later, Hill described the secrets he learnt in Think and Grow Rich, the classic guide and all-time bestseller for success in money-making endeavours. Hill authored over 30 books and acted as an informal adviser to Presidents Woodrow Wilson and Franklin D. Roosevelt. The motivational pioneer died in 1970, but his wisdom lives on in Think and Grow Rich, which has sold an estimated 100 million copies worldwide.
