If you could send a message to the entire world, what would you say in 30 seconds?

I'm quite curious what kind of message will NBB users will sendif they'll be given a chance to send a message in the entire world (in 30 seconds) Haha

It can be any message. English or in Native language.Inspiration or whatever.

As for me. I probably say "Hey Yorhey, yes you are! You still owe me $15 from 5th grade! When will you pay me?"
