I have three of sorts.

I keep a large journal of art work. Some of it is painted or scrawled right on the pages, sometimes it is pieces fo larger work pasted in. I even have work that I've sewn into some pages. Occasionaly I write inside this journal but I try to keep it to inspirational quotes and positive ideas.

I am always working on a written journal. I will often though go back and rip out pages of that which was particularly negative. I don't keep my journals for the very reason that all is not positive and I really don't need to reread about difficult periods in my life. A word of note: it is incredibly easy to find yourself ruminating and focusing on the negative. Having twice put myself into the hospital after such rumination plunging me deeper into Depression I have promised myself to make the effort to try not to do so.

My third manner of journalling is maintaining a blog. It isn't always so positive either. Amongst positive reflections and creative writing, I do find myself laying into rants of sorts. Often my blog becomes an extension of this forum. Sometimes it is a continuation of my ideas. The thoughts tend to run the gamut of positive commentary to critical discussion to outright rants. I find that 'completing' my thoughts on a subject to be therapeutic.
