If you are like me and have too many half finished or unfinished notebooks and journals, you will want to read this: Why it’s so hard to finish a notebook or journal – Vox.
I can’t say reading that piece will help you finish them, but it will help you better appreciate some of the difficulty MANY of us have with doing so.
My take on it is: buy ones that are either small or have pages that are easy to tear out. After awhile go through old ones and tear out things of note and then toss them aside. And then go buy more! 🙂
