Probably one of the most powerful tools man has. And yet so poorly understood, or so blithely disregarded.
Everything man has ever created was first in the mind. From basic ideas to great inventions. That a writer first conjures the story up and then puts it on paper is simple to understand! Really logical. But do we understand what that means? Thinking about the power of thought usually ends here, with the finished project. Once the work is done and the product sees the light of day, we no longer attribute any power to thoughts. As if we froze our ability to creatively think and to have things materialize in physical form until the next project.
Supposedly, humans have about 70,000 thoughts a day, mostly at a subconscious level, but they all affect us. Our lives, the way we think, our habits, our opinions, how we look, who we surround ourselves with, how we breathe, and who we like and/or dislike. Whether we believe it or not is utterly irrelevant.
