Give guests a job to make them feel at home when they're in your home.
When you're hosting a dinner party, it's almost a kneejerk instinct to refuse help when your guests offer - even if you could use it! But most people aren't offering a hand out of polite obligation; they really do want to be part of the fun behind the scenes. Next time someone offers, give them a low-stakes but high-reward job like setting the table, pouring the wine, or helping you plate the food. They'll feel more invested in the party, and you'll have one less task to worry about. Win-win!
