The research and writing of Think and Grow Rich lasted over 20 years. Ultimately Dr. Napoleon Hill sold over 30 million copies. As for his personal influences, he did write a letter to Charles F. Haanel to say that Haanel's Master Key System had much inspired him and changed his life.
Throughout his life, he spent a great deal of time teaching and helping others to learn the laws of success.
