Answer:
Prayers lead to frustrations due to the fact that we are not patient or we are thinking it too much. It is not God's fault, it's just that we can't wait. I said it so because if you are really expecting it and you're just light-headed about it, the more chance it can be true or happen. Believe in Him, He'll make your plans more than what you wish to happen. He's a writer of our story. Do not lead Him, let Him lead you.
