14,000 Things to be Happy About - Ann and Barbara Kipfer, Workman Publishing

Originally published 25 years ago (happy anniversary!) from a list that Barbara Ann Kipfer started making as a child, it's the book that marries obsession with happiness. And it now has 2,000 fresh and more current reasons to be happy: Rabbit tracks in the snow. Kiteboarding and kitesurfing. Caramel gelato. Scoring super-high on a Scrabble turn. Babies burping. Summer storms. White cupcakes with multicoloured sprinkles. 20 minutes all to yourself.
