Simple and free deeds work too! Acts of kindness, such as surprise notes of encouragement and affirmation, are an excellent way to share the love. Mention to your friend that you’re sprinkling the world with extra kindness to celebrate their birthday. Jot down a few kind words and leave them in ordinary places where they will have extraordinary impact. Tape your note to a park bench, leave it on a library shelf or sneak it next to the baby formula in the grocery store.
