The first key to faith is to ask God for His vision for your life! We all need Jesus Christ as our Savior to have new life in God. We can then ask God to give us His thoughts so that when we pray we will be asking for His will for our lives.
The second key is to ask prayers according to the Bible. The Bible is God's Word for all of us, and if we ask according to the Bible we are asking in accordance with God's will and plan.
The third key is to believe God will answer and to wait patiently. The Bible says God is our great and heavenly Father; if we know how to give good gifts to our children, how much more will our Father in heaven give good gifts to those who ask Him. God may not answer your prayers right away, and He may not answer them exactly how you anticipate. But wait in faith, expecting Him to answer, and God will answer your prayers!
