What do I want to be when I grow up?

From 1919 to 1920 Hill was the editor and publisher of Hill's Golden Rule magazine. It was during this time he wrote a letter to Charles F. Haanel in which he praised his book The Master Key System. In the letter he writes: "..I believe I ought to inform you that my present success and the success which has followed my work as President of the Napoleon Hill Institute is due largely to the principles laid down in The Master Key System."
