You think those without money never think of money ah?

I think they more stressed out.

Rich people treat chasing money as a passion, a game in which they go all out to win. They know they actually dont need the extra money, but they do it anyway because it gives them great satisfaction when they achieve their goals/targets.

Some are misery of their hoard, but others are generous. After they attained their millions they give away some to charity. But they will continue to chase money because of the adrenalin rush, just like why some people love fast cars.
