Neville Goddard 
Be What You Wish 

Most men are totally unaware of the creative power of imagination and invariably bow before the dictates of ‘facts’ and accepts life on the basis of the world without. But when you discover this creative power within yourself, you will boldly assert the supremacy of imagination and put all things in subjection to it.
It is believed that all men can change the course of their lives. By our imagination, by our affirmations, we can change our world, we can change our future. If we strive passionately to embody a new and higher concept of ourselves, then all things will be at our service.
