It's more about getting thoughts out of your head. I don't really do it to make any particular note of my life. I find that sometimes it's just nice to be able to dump thoughts on to a page (I only journal on paper) and maybe make a bit more sense of them.

I find that if you start writing without any real goal in mind, just whatever you're feeling or whatever's troubling you, it might uncover something to you that you hadn't considered. A new perspective, maybe.
