There is a theorem say that:

• The longer you are in a dengerous area, the more chances you will get accident.

This statement seem to be true, that why you need to drive faster on the road so you can get out from the dengerous area as fast as you can to prevent from accident :)

From this theorem, we also conclude that

• The more work you done, more error you will get. The more error you make, the less chance you get promoted. The best way to prevent error in your work is to not to do it.

That why those people that do not work can get promotion and rewards, but those who working hardly will get nothing.
