Law of Success, livre audio

Napoleon Hill is well known for writing inspirational books about achieving success in life.
Probably his best known work is "THINK AND GROW RICH" written in 1937.
Some 10 years prior to that, he published a book called "LAW OF SUCCESS", originally as an eight-volume work, which was presented by himself as a series of lessons. This series was subsequently revised into its present format - that of 17 lessons, here presented as an audio course.
This course deserves to be taken seriously, for it contains excellent advice on a number of self-improvement subjects, and has been proven to contain the keys to success, both on a personal and business level.
Note: These audiobooks are based on Hill's original writings, so there have been significant developments in technology since the book was written, and some things will have changed. However, the basic principles, especially as they relate to personal development, are as applicable today as they were then.
The 17 lessons cover the following:
Introduction
A Definite Chief Aim; How to develop your major purpose in life
Self-Confidence; Mastering your fears
The Habit of Saving; Making the most of your money
Initiative and Leadership; How to become a leader
Imagination; Stimulate your Mind
Enthusiasm; In everything you do
Self-Control; Manage your enthusiasm
The Habit of Doing More Than Paid For; Going the extra mile in all you do
A Pleasing Personality; Removing obstacles in life
Accurate Thinking; Classifying information
Concentration; Improve your focus
Cooperation; Get on with others
Profiting by Failure; Make the most of mistakes
Tolerance; Get on with others
Practicing the Golden Rule; The universal law of human conduct
The Universal Law of Cosmic Habitforce; How to put into practice all the lessons learned
Most importantly, this is NOT just a book to be read, but the principles taught are meant to be practiced consistently, with absolute focus and commitment. A better foundation for success you will not find!!
