Right now, I'm loving coming home to my new husband. That puts an immediate smile on my face.
I also love watching him interact with my cats. He loves them as much (well, almost as much) as I do. We thought we might lose Sophie Kitty earlier in the year, so to see her sitting on his lap each night makes me smile.
Ice cream. Seriously, I have a problem. 
On Friday, I noticed that the trees were starting to flower. That definitely made me happy.
There's a little boy--Collin--whose father is a regular on another forum I frequent (I think Snap has mentioned him here a time or two). He's had a long and scary battle with leukemia, but he turned a corner about a month ago. Every time I read an update indicating that he's getting better and better, I smile (and tear up).
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
