I often buy a calendar notebook in December. It’s one that I will use only for writing, so I give quite a lot of thought to it. This year I splurged and bought a lovely Moleskin. My intention is to set daily goals of some sort. If I’m at a first draft stage, I will set daily word goals, but I’m not at that stage yet, so I may only set daily thinking and research time.
This calendar rarely stays with me for more than a few months, but at least it gets me started.
