“In the place where I am now I look back over my life. I look back at the world I’ve left behind. What message do I want to leave? I want to make sure that you all understand that each and everyone of you has a role to play.

“You may not know it. You may not find it. But your life matters, and you are here for a reason. And I just hope that reason will become apparent as you live through your life. I want you to know that whether or not you find that role that you’re supposed to play, your life does matter. And that every single day you live, you make a difference in the world and you get to choose the difference you make. I want you to understand that we are a part of the natural world.
