Einstein reputedly divided people into two groups, those who believe we live in a friendly universe, and those who don't. Brilliant in its simplicity, it points out the fundamental basis of wellness psychology - that a well mind knows that we live in a friendly universe, brimming with opportunity and potential, awaiting our actions to trigger their manifestation. A good mind sees abundance and realizes that there is enough so that each of us can have plenty.
A good mind is aware of and utilizes the law of attraction, and understands how consistency with nature and things natural makes sense and produces better overall results. Avoiding "lack thinking" and inappropriate, unnecessary pessimism conserves valuable energy and resources, to invest in productive and gainful behaviors.
So, wellness psychology helps you become rich because a good mind is attractive, supple, creative, effective, capable, curious, motivated, and persistent. Remember that being rich is not only a matter of money, but a manifestation of inner wealth as well - rich relationships, rich appreciation for the splendor of natural living, and rich life experiences also respond to prosperity consciousness. Positive expectancy and positive, powerful action toward a worthy goal create the best probability of success and fulfillment. (See The Dynamic Laws Of Prosperity by Catherine Ponder)
