An unexpected gift, treat, or bonus comes winging your way when retrograde Mercury forms a trine to Jupiter on December 18. It's just the sort of thing to brighten your day and boost your holiday spirit. And of course the only thing better than getting is giving as far as you're concerned. That’s what happens when you're born under Jupiter, planet of munificence. You can't help paying forward the good fortune you've been shown. Jot down the names of those you know feel overlooked this Holiday season and play Secret Santa. Nothing beats watching people try to figure out who surprised them with a gift.
