I don't journal, blog or write anything. The most writing I do is here on PC. I've tried in the past but it just isn't for me. I'm a very visual person tho. I create visuals in my head that reflect whatever I am reflecting on. I can recall the visuals too. I even dream like this.

I don't know a lot about writing tips, I would just let it flow freely, not worry too much about subject matter, or controlling what comes out, maybe just to get a start.
