Where is my heart?

I can't really date for a year. Its part of the student missionary policy. It makes sense. But I'm doing it for my own reasons, not just to conform. I give my heart away to much to girls. I've been carelessly throwing it around to the nearest and most available girl that catches my attention. Where does God fit in this picture? So instead of giving my heart out to them, I'm giving it to God. He deserves it and so much more from me.
