Money

Everyone works and works for more money. But you can never have enough. All you have is paper from a tree but it can buy you almost anything. Even if you're the richest person in the world, such as Bill Gates, you still want more and more money. He has over 15 billion dollars more than anyone in the world needs but he still wants more. Why is it that we always want more stuff, nothing is ever enough for us. But i guess that's just people, we always want, want, want.
