The goal isnt sinful sefish desires being met. 

Man's Prayer doesnt make God do things. He doesnt exist to do what we want, quite the opposite. And we (who walk in truth and the faith) dont say well God isnt doing what I want [including answering prayers the way I want them answerd], so phowey, or whoa as me. No. Prayer is to 1. Communicate with God, and 2. align ourselves to God's Will. 

....And prayer itself is a privilege.
