If the World Is Endin' Tomorrow

I can't help myself to think about this question today. If the world is end tomorrow, what can I do, or what should I do...? Can't believe that someone gonna leave one day. Why do I feel scared about that? Why do people feel scared of the world's endin? We haven't finish our life goals? We havn't made our work excellent? We haven't told someone that we love her or him? We haven't had a travel around the world? We haven't protected our important ones? We haven't done this week's plan?...If the world is coming end tomorrow, what would you gonna do?
