Praying the Psalms

If we are being completely honest with ourselves we tend to get very repetitive & uncreative in our daily prayers. We might thank the Lord for the day and then ask him for a few things from off of our needs list. Maybe we throw out a prayer for our wife & kids and maybe on a really spiritual day we even pray for the poor and needy! But it seems that our prayers never get much deeper than that and deep down inside we convince ourselves that praying with all of our being is just meant for those spiritual or fanatical Christians. So we just keep going on day by day with our heartless religious prayers. So we ask ourselves: What's the solution? What if I'm just not that creative? I've never been good with putting words together how do I know what & how to pray? How do I keep thinking of new things to say to God?
