‘Think and Grow Rich,’ by Napoleon Hill
Napoleon Hill, a Great Depression-era author and former adviser to President Franklin D. Roosevelt, interviewed over 500 successful people to figure out the key to their good fortune. He shared his insights in “Think and Grow Rich,” one of the best-selling books of all time.
Hill’s six-step plan to building wealth is based on deciding exactly how much money you aim to earn and what you’re willing to do to get it. (It’s not as ominous as it sounds.)
