Those are just a few things that came to mind. If I had the time to prepare something more lengthy I would try to put something together saying something along the lines of what I said above but with more substance. 😉
I wouldn't speak at all actually. Today's society probably would not even listen, you will either be judged, somehow offend someone, or who knows what. =P
I probably would mention that everyone needs to stop taking things so seriously. For example, the police aren't out to get you, when they stop to ask you a question.
This is really a new question here, but really amazing it will describe how much are you creative. So my answer would be here if whole world is listing to me, I say everyone to enjoy the life without hurting anyone. We are on earth to enjoy not only for earning money. Earn only enough that you can enjoy.
