I have read this book many times and I believe that it holds the keys to help any person in any area or business or personal endeavour to achieve what they wish to achieve. The manuscript was first published in 1925, then in book form in 1928 and updated many times over the years to include more modern examples. The principles hold true and many of the modern day self improvement gurus use variations of these principles.
You can purchase any of his books, and he has quite a few from Amazon – “The Law of Success”, “Think and Grow Rich”, “Success through a positive Mental Attitude” and many more.
But to get a true feel for the man himself, spend some time, watch, learn, and put into action the principles in this video and you too can achieve whatever your mind can conceive and believe.
