The Master Key System

The book that will not only leave you 'feeling' good but also 'thinking' good.




In The Master Key System, presented as a series of 24 lessons, Charles Haanel discusses everything from how to feel healthy to how to become wealthy. Using precise logic and a consistent, common-sense framework, Haanel shows us how to achieve that what we most desire. The Master Key System is rumored to be what inspired Bill Gates to leave Harvard and start Microsoft, and was also one of the main inspirations for the best seller The Secret.
