Psalm 37:3-5
Trust in the Lord, and do good; so shalt thou dwell in the land, and verily thou shalt be fed.  Delight thyself also in the Lord; and he shall give thee the desires of thine heart.  Commit thy way unto the Lord; trust also in him; and he shall bring it to pass.
 
Unfortunately, we often pray with selfish motives.  As this verse says, our focus should be to delight ourselves in the Lord.  If our aim is to deepen our relationship and worship with God, then he truly will give us our desires.  There is nothing more valuable than this.  No rating points, no new Ferrari, no house, no job, no celebrity status can compare to this.
