Well, I didn't write something every night, but I wrote a significant amount several times, and it helped me process some things, so it was pretty good. It might be useful to reread it, but I really hate reading my own writing. We'll see what I end up doing.
I found that I could really write a lot, which was surprising. And I could have written a whole lot more, since writing about something brought up other things. It probably helped that it was a rather emotionally-charged time for me. Writing helped me clarify some of those emotions and come to some decisions. It certainly is a lot different writing down something that I'm not planning on showing anyone else than it is writing stuff in a public place, like here. I think it might be a good thing to keep a paper journal. Yes, I could jsut do private posts here, but it just doesn't feel like something I want to do. Among other things, when I'm writing about really important things to me, the physcial act of writing things out feels good to me, feels right.
