I'm amazed at the big effect a little thing can have.  

The little stickers I invented during my cancer treatment are a good example. They seem small and simple, and they are, but they have made a huge difference in the lives of people all over the country. That makes me happy of course, and it got me thinking about other ways this can happen in our lives. 

Try this simple experiment: Think of someone you haven't spoken to in a while. Take out your phone and send them a text saying, "Thinking of you, and sending love." It's amazing how such a small gesture can make a big impact. I did it once at an event, and years later, I still remember the effect it had. Give it a shot and see what happens! 😀
