One thing that works with some people (but not nearly all of them) is to figure out how much you make vs. how much you work and come up with an hourly rate. If you make $1,000 a week and work 10 hours, then every time someone talks to you for 6 minutes say, "Thank you, I just lost $10." If they drag you out to a movie say, "That was fun! But it cost me $250!"
