The important thing is how we respond to our situation. We can transform anything if we respond in a skillful way. This is precisely what karma is about. If we greet situations with a positive attitude, we will eventually create positive returns. If we respond with a negative attitude, negative things will eventually come our way. Unlike the scenario in the movie, it doesn't always happen right away. We can be very nice people but still have lots of problems. On the other hand, we can be awful people and have a wonderful time. But from a Buddhist perspective, it's just a matter of time before we receive the results of our conduct. And usually it is true that people with a positive attitude encounter positive circumstances. Even if the circumstances do not appear positive, they be transformed through a positive view. On the other hand people with negative minds complain even when things are going well. They also transform circumstances, but they transform positive ones into negative ones!
