What to write?

So what do I want to write on my blog? The easiest and most tempting thing to write is whats happening in my life, what I think about myself, others and my surroundings, any comment about the general happening in the world or some philosophical garbage that no one wants to read.

I can tread the oft-used path and write something funny based on my experiences with the world. Thats something interesting and can be written.

But finally the question remains. What to Write??
