Before the Secret, there was the Master Key... Charles F. Haanel, the author of this book, has been regarded by hundreds of people as the "Father of Personal Development". Rumor has it that while he was attending Harvard University, Bill Gates discovered and read The Master Key System. It was this book that inspired Bill Gates to drop out of the University and pursue his dream of "a computer on every desktop." And the rest they say is history . Silicon Valley also has a secret and it's that almost every entrepreneur who made a fortune in recent years did so by studying the teachings of "Before the Secret" which was written over eighty years ago! Countless self development books have been based on these teachings which can be found in "Before The Secret". The teachings have been shared in the movie and more recently on Oprah with the students of these teachings.
