go to a bookstore and leave little love notes in between the pages of random books: "your smile is stunning," or "someone, somewhere is thinking about you right now."
bake a cake, add candles, and gift it to someone for no reason at all. have them wish on it.
call a friend just to say, "hi"
what did i forget? let me know in the comments below how you spread kindness into the world around you.
