Think and Grow Rich has earned the reputation of being considered a textbook for actionable techniques that can help one get better at doing anything, not just by riches and wealth, but also by people doing wonderful work in their respective fields.
For more than a decade, the author interviewed some of the wealthiest and most successful people in the world and based on what he learnt in the process from all these people, when asked about how they achieved not just great riches but also personal well-being, he formulated hundreds and thousands of answers, into concise principles which when acted upon, can help one achieve unprecedented success.
Think and Grow Rich teaches not just concepts but also methods. It is not a book that a reader can use for one time consumption and has to be read one chapter at a time and in sequence.
