How to pray to God

I often find it difficult to concentrate during prayers. The mind wanders about from one thought to another, and then I complain "why doesn't God answer my prayers?". Perhaps the problem is not with God not answering, but the way I'm asking.During prayer, instead thinking that God is somewhere high up in the sky, we should pray by whispering softly to Him knowing that He is very close to us and loves to hear our Prayers.
