Don't throw away prayers because you are discouraged when it doesn't seem to work.
Be steadfast,faithful and have faith in God.
Prayers that work isn't merely a matter of
gift or personality.
You must be positive and see God answered your prayers even before he does, that way we already have faith that he has answered our prayers and so physically our prayers would definitely be answered by him.
We just have to be faithful and believe in him for our prayers to be answered.
