Too many folks have wants that they believe are needs. These are the people that will grasp beyond their means to have that "need". Often, you need to place that impulse on the back burner and see if it still burns as bright in a few weeks. That's one way to determine the difference between a want and a need. I see more of this as impulsive rather than obsessive. An exception I can think of would be the lifelong obsession with power. Some people want it, think they need it, and the truth is, we really NEED and WANT them to go away.
