Journaling is the purest, rawest form of writing.
If you don’t like the idea of a diary, create a journal for a fictional character. Get to know them, then write your story.
Live to live, not to record. Never let the magic of the moment be lost because you were too busy writing it all down.
I’m a scrapbooking collagist when it comes to journaling, meaning heavy on the photography & “graphic design,” & light on the writing. I’ve included newspaper clippings, greeting cards, event programs, badges (for example, my college press pass), & many more.
Always have a notebook (& pen) nearby: on the nightstand, in the glove compartment, in your purse/murse, etc. Ideas often come at the most inopportune times. It’s easier to keep up with several books rather than having to remember to always carry the same one around with you (unlike a cell phone).
Have a “theme” journal. Joe Brainerd did an “I remember” theme. https://www.poets.org/poetsorg/text/joe-brainard-i-remember. I am doing a “Precious Moments” book for my daughter. Other ideas would be “What if?” (my favorite poetry subject), “If only,” &, in the spirit of Tom T. Hall, “I Love.”
Start a reading journal (this is best for poetry). Unlike a book review, which analyzes the text with a critical eye, a poetry reading journal is about what the text means to you.
Journaling isn’t just about the product, but the process. If you focus too much on the product, you’re editing, not writing.
In the Irish film, The Secret Scripture, the main character has a Bible in which she keeps her journal, writing in between the lines, in the margins, et cetera. You can do this with any book that profoundly affects you.
Though there’s something intrinsically beautiful about a handwritten journal, don’t feel you have to write your journal by hand. (Better to keep a digital journal than no journal.) There are many journaling apps online. Think about it. Most of already journal every day, whether it be through Facebook, Instagram, our Shutterfly Share site, WordPress blog, etc., though hopefully, we’re not posting our deepest, darkest thoughts—that should be between you & your journal, whether on paper or paperless.
