Interesting blog post by Dale Shanklin on using different journals, once you get past the title; there is no way to “journal properly” you just do what feels right for you. But I digress.
I think the three categories, Daily Progress, Problem Solving and Idea Pad, are a great way to focus and organize your writing. I also write in different journals although they are not organized in the same fashion.
I might add a fourth journal into the mix: Anger Management. We all need a place to vent frustration and sarcasm and a journal can be an excellent safe haven for your feelings, no matter how homicidal. 🙂
