2012 is already happening..... We are evolving to a higher state consciousness and we have the choice of peace or war.
You manifest the world you live in and now that 2012 is here it is 100X stronger so think positive, loving, feelings..... Avoid the drama and the karma that comes with it.
I will go to bed as normal on that night and wake up the next day. I don't concern myself with what may happen. I am just happy enjoying this moment..that moment. Oh, its gone already. See. there that one goes, and another one and another one....
