Who do I write to?

I'm in a bit of a dilemma...  I really really want to be a writer but I don;t feel I have anything to write about that anyone else would give a damn about.  I have read that you need to write for the sake of writing first and then the rest will come.  Well, I'm waiting and still the words don't seem to come.  I'm going to keep waiting I guess...  My time will come and when it does I hope I can change the world, mind at a time.
