I find this sort of belief quite interesting, especially when it is predicted on numerous occasions, throughout history. In my opinion, the whole 'end of the world' scenario seems more like a method to try and control a large group of people to do certain things, eg, abide by the Christian faith, etc etc. Which, in my own humble opinion, is exactly what religion sets out to do - to control the population. You only really need to look at the Hindu caste system to understand the idea, and the powerful tool religion can be in the manipulation of the masses to do the elite's wishes. I came across this video a while ago on youtube, and it illustrates my own point/view pretty perfectly:
If you believe the world is ending soon, you can if you want to. It's your own call. But as with most things in life, ideas should be questioned and evaluated- otherwise the only result is continuity. Just my 2 cents, anyway. Discourse is always healthy!
