I agree with Alex that money as a concept can be a problem if it becomes an obsession. I also agree with him when he says it can be a good incentive to improve your otherwise discouraging circumstances.
If we review that recent Will Smith movie, "The Pursuit of Happyness," it makes good points. Smith plays Chris Gardner, a man who's incentive to get his life in order is his kindergarten-aged son for whom he becomes the sole provider. Some of the hardest experiences he deals with include spending nights in homeless shelters and train station bathrooms because he has no money. Yet, he is motivated to get accepted into a stock internship program and uses his resourcefulness and ingenuity to turn his life around. He desires to earn more money, but money doesn't run his life.
To borrow the quote offered by trekr5: Oprah says "I can see how being poor will help anyone." Consider the lives of people like Mother Teresa, Mahatmas Gandhi, Martin Luther and others who have had dreams to change the lives of the less fortunate. They did more than inspire without having lots of money. We shouldn't limit our thinking to believe that we must have money to make a difference.
