 The person who walks according to the will and the word of God will pray prayers that are aligned with his will and God is not going to say no to his own will. In other words, when you pray with the Holy Spirit desires, when you pray with the Holy Spirit wants, when you pray with the Holy Spirit has planned, then and only then are you guaranteed that your prayers will be answered. No exceptions. And that's a promise from Jesus. So the key is not in convincing God to do what we want to do. The key is in praying the will of God. Not in trying to change the direction of the river, which is God's will, but rather in jumping in the river and saying take me where you want me to go.
