You get a TV that fits your house. But you want a bigger house. Then, the TV seems too small, the house seems bare, and your car is not nice enough for the neighbhorhood. So you get a bigger TV and fancier car.
Now, you have too much stuff in your house, it is too small again! So, you get a bigger house...
