Such a moving tribute

I listened to the radio today. It reported that Australia cricket captain Michael Clarke broke down in tears when he paid tribute to Phillip Hughes at his funeral.
It was a very moving tribute as he spoke from the heart. 
This started me thinking about all the people who are passionate about what they do and what a difference they make to others.
You don't have to be famous to make a difference. 
For me the key is whatever you do needs to mean something to you. If you do what you are passionate about you make a real difference to the world.
