I have picked up a book by Charles Haanel again. I have blogged about him before and I can not stress enough how great this book is for the "mind shift".
He believed that mind in action is a thought, and thought is creative. Men are thinking now as they never thought before. Therefor, this is a creative age, and the world is awarding its richest prizes to the thinkers. Matter is powerless, passive, inert. Mind is force, energy, power. Mind shapes and controls matter. Every form which matter takes is but the expression of some preexisting thought. But thought works no magic transformation; it obeys natural laws, it sets n motion natural forces, it re lases natural energies; it manifests in your conduct and actions, and these in turn react upon your friends and acquaintances, and eventually upon the whole of your environment. You can originate thought and since thoughts are creative you can create yourself the things you desire.
His ideas are extremely perfound, specially, when you learn that he said it in 1912. This book(which actually it's more a system than a book) called The Master Key System, is simply one of the finest studies in personal power, metaphysics, and prosperity consciousness ever written. Read it if you can!
