writing for the sake of writing

I've been writing lots of material for the sake of writing (http://project05952381.blogspot.com/2010/07/my-writing.html). Maybe it's my desperate attempt to achieve something or simply prove something to someone -- myself perhaps. Nonetheless writing lots of material makes me a better Christian or person for that matter. Anyway the question remains then. Why am I writing for the sake of writing? Maybe I'm so bored that I need to kill time writing.
