Such pronouncements have their place as an expression of people's amazement at events reported through third parties and spread as mantras for living life to the full in the here and now. Plan not for your plans will come to nothing as this earth is torn by destruction. Should you choose to believe in such pronouncements, you can party with abandon enjoying the delights of the flesh without feeling the guilt of your super ego's remonstrations to calm and more deliberative action of a preservative kind to maintain balance and sobriety.
The truth is that we cannot say whether as an individual our worlsd might not be shattered by the dangerous forces that will inevitably sweep through the world in 2012. That the world is or will be any different from what it is or was in the past we can be sure that the answer is no. No the world or worlds will not be destroyed in 2012, just as the worlds were not destroyed in previous speculations of its coming end. No cataclysmic fire will blow us all to smithereens. Some fires may end a few of us, but for the majority, 2013 will be a period of immense joy and growing security as we turn the tide of our failings and increase the abutments to a strong and definable future.
Will ye no think kindly on those who would be your friends! May the sun shine with your thoughts, today, and happiness grow in your heart! May you allow yourself some peace of mind.
