"I make my own luck"

In the movie batman, one of the characters told his fiancé that he makes his own luck and that's why he was always lucky and became successful until later events forced a change of mind. Many people waist their life wishing they were in someone else's situation saying that they are not lucky or that person is so lucky. What people should realize is that they shouldn't let the situation control their life and they have to start determining their own future and make their own luck.
