Fredric Lehrman in his audio course, Prosperity Consciousness, bases his exercises on three Laws of the Mind, strikingly similar to how Newton based the results of his Principia Mathematica on three physical laws.
Fred's audio course is about leveraging these principles to improve your physical (money-based), mental (self-assurance based), and spiritual (putting your values into the world) existence. However, the principles can leverage many other endeavors as well. Fred's technique is: be aware of subtle inner grumblings about what you are doing, and change the thoughts behind them by disciplined writing down of more correct versions of the thoughts until they stick.
