Running into a friend at the mall who happens to know of the perfect place to host a family reunion that's within budget and has all the amenities you could ever want...that's serendipity.
Stumbling upon a yard sale where you are able to score two entire book series that you've been wanting to get for a very long time and only having to pay a dollar per book (or less!)...that's also serendipity.
Having someone offer to become a volunteer in a needed position at your kids' school just as another volunteer informs you they can no longer help, finding the perfect Christmas gift and then discovering it's 80% off, finding that long overdue library book just as you're ready to pay to replace it...
Serendipitous events happen on a daily basis. You just have to learn to recognize them when they come. Then count them in your blessings.
For gratitude is one of the greatest dragon-slaying tools you'll ever find.
I believe in serendipity. I celebrate it, treasure it, and applaud it.
