What would you tell the world?

Imagine you had an audience that consisted of the entire world.They could all hear you and were all listening.What would you tell them?Would you tell them about the state of Africa, the morals of the world, the christian values that you might or might not uphold? Would you talk to them about music, happiness, money, shame, fear, death, life, survival?In fact, could you even do it all? Apparently public speaking is the biggest fear in the world. I personally can't believe that because I love public speaking and presentations. But I know a few people who firstly wouldn't be able to speak to the ENTIRE WORLD and secondly would have nothing to say.What would your words of wisdom be? What would the thought be that you impart?
