Some advice on what to pray for from Saint Augustine:
Stretch wide the net of your insatiable desires, greedy, and find something greater than God, find something more precious than God, find something better than God. What won't you possess, when you possess him? But all right, rake in to yourself gold, silver, as much as you can. Cut out the neighbors; keep a tight grip on your estate by enlarging it, till you reach the ends of the earth. Having bought up the whole earth, add the seven seas. Let everything you can see be yours; let everything under the water which you can't see be yours. When you've got all this, what will you have in fact, if you haven't got God?
So if by having God a poor man is rich, and by not having God a rich man is a beggar, don't ask him for anything except himself.
(Sermon 105A, from Essential Sermons, New City Press)
