A Gazillion homes

I think I must have shown at least 20 homes over this past week.  What can I do to CLOSE a deal?  Is there a better way to ask for the sale?  I would welcome anyones input.  Unsure if it is simply the market or my approach.  Of course, my approach is not the same with each client, however, I do always ask for the sale.  Oh, I do have my first closing, on my first sale at the end of this month.  I am looking forward to that and hope for many more to come.
