Be single minded about what you want to achieve. Hannah prayed for a son not a baby or a healthy child (1 Samuel 1:9-28). She stayed on her knees, made a deal with God. Did whatever she felt was necessary to get the outcome she wanted.
Be very clear in your mind about what you want and do not waiver. The clearer you get the more you will see the universe conspires to bring it to you. God is turned off by people who are double-minded and unsure of what they want.
