Have enough faith in the love of God to believe that a short heartfelt prayer is just as good as a long one. Too long a session of prayer usually means that in your heart you really doubt the love of God, and think that a great deal of effort and toil will be necessary to move Him. Pray quietly and sincerely for a reasonable time-and then leave the matter, expecting success.
