What exactly are you trying to ask ?
Anyway, this is what i would do -
1 - Go into a cave and come out once in a while. While I am at it, write a book on how the world will end.
2 - Say nice things to people and become popular.
3 - A few days later, declare that i have had a vision that the
earth will be destroyed. Show them the book also.
4 - Relax and watch the people i mentioned above spread the information.
