As the Chinese saying goes, "Wealth does not enter urgent doors."
The following, from Rhonda Byrne's excellent book The Secret, explains why this is the case:
"If you do not have enough, it is because you are stopping the flow of money coming to you, and you are doing that with your thoughts. You must tip the balance of your thoughts from lack-of-money to more-than-enough-money. Think more thoughts of abundance than of lack, and you have tipped the balance."
"When you need money, it is a powerful feeling within you, and so of course through the law of attraction you will continue to attract needing money."
