This is one of the most cited self-development books in the world, ranking alongside the works of Dale Carnegie and Napoleon Hill! James Allen wrote a book in which he first found the very idea that thoughts underlie all changes in life. More than 100 years have passed, but it seems that the book was written by our contemporary, it still remains relevant, and the advice given in it is quoted in many best-selling books on self-development and working with thoughts. From this book you will learn how to achieve personal and professional success through managing your own thinking, how to learn to use the power of thought to change your attitude to life and behavior.
