Why write?

I haven't written in a while.

It's not because I have been without ideas.

It's not because I haven't had time to put these ideas into words.

It's not because I have started thinking that people read what I write now, because of which I'm self conscious and have started worrying about how it may be received.

Why do I write? Not why does one write, why do I  write?

I have not thought about it too much, the simplest answer to it is "because I like writing". That's not it, by the way, but for the sake of simplicity I'm going to leave it at that.

So if I enjoy writing and I constantly have images, phrases, analogies, ideas, etc that could be made into blog posts in my head. Why not just put it down on paper, in this case via keyboard onto screen?

I do not know.

I don't know. I just don't. And it's not only writing. There are many things that I know I should do, I can do, that is the only thing to do, the only thing that makes any sense. Yet I don't. Why not? I don't know.
