From walking on the moon in space suits to careening along canyon walls in wing suits man keeps pushing back the boundaries of the inconceivable. The more impossible, the greater the challenge, and the more positive the vision. In 1952, a Methodist minister, Norman Vincent Peale, wrote the bestseller “The Power of Positive Thinking,” a book that received heavy criticism at the time. Since then, churchgoers have increasingly flocked to hear the same message. Devotees of personal empowerment now listen to headsets on their way to Wall Street trading. “When we smile, the world smiles with us.” Attitude creates our perceptions; the way we think not only transforms the world around us, but the physical world within us.
More and more evidence assures us that the beaming positive attitude that works miracles around us also directs both the production and maturation of stem cells within us, directing the output of our immune systems, and reversing disease. A strong belief in the power of self-healing boosts the output of cytotoxic T-cells that attack and engulf cancer cells, and makes us healthier every day. Happy people know this and live longer, too.
Happiness doesn't depend on any external conditions; it is governed by our mental attitude.
Dale Carnegie, 1948
