Such things happened in the lives of many people. Even to find the source of which many people put forward different opinions. But i am limited to the following two issues.
1. By her luck
2. By her hard working
I think both can work together with anybody, especially if that person has the luck. We can also get rich if we are hard-working, and we can found a perfect job that can give us big money. With more luck, the chance to become rich will be bigger, and that can change from the poor man's becoming rich quickly.
