Napoleon Hill's Cycle of Thought - a book to inspire your positive self. This upside down book replicates the cycle of thought. Positive thinking does not just "happen," but often occurs in tandem with the outgrowth of negative thought. If not for loss, a person might not be able to appreciate a gain in finances, relationships, and employment among many other circumstances in life. In order to focus on the good the bad needs to be acknowledged. This cyclic balance demonstrates the ebb and flow of the Universe constantly in motion both for and against itself.
