My friend Meredith and I were out walking on a busy street this weekend. We walked by a woman wearing this shirt. She greeted us as we passed her on the sidewalk with a big smile and cheerful "hello". Those are the people you want walking around -- making your day. Such a simple, friendly message has the ability to create such positive energy. I'm proof. It's five days later and I'm still thinking about a stranger who I passed randomly on a city sidewalk.
(This is not a picture of the actual shirt she was wearing. That would have been slightly creepy if I then asked her to stop so I could snap a shot of her shirt...)
I found this link in my inbox this morning... it's an interesting article and good food for thought. Take a second to read it -- and see if it's something you want to apply to yourself and your life, in some capacity.
