A Random Act of Kindness a Day to Change Myself and the World

I've decided to do a random act of kindness a day to see how it impacts my life and the world in general. If nothing else, I know that doing good for others makes me feel good, so it's a good experiment from the start!

The first random act of kindness I am going to do is in the picture above - write a "thank you" note to someone who has impacted my life positively.  

I'd love it if you'd join me. What are your ideas for random acts of kindness?
