If you're not in the service industry, celebrate by planning a night out at your favorite bar or restaurant.  Just because the holiday is technically for someone else, doesn't mean that you don't deserve a celebration, too!  Share the love by increasing your normal tip by at least 5 percent.  So if you're normally a 15 percent gal, take it to at least 20!   

If you are in the service industry, have some friends over to your place for a white wine and spa night!  Invest in lotions and treatments for hands and feet.  Remember to treat YOU on that special day.
