I've kept journals in one way or another for many years now, though I'm always trying out new ways to record my ramblings. This year I've been using a Hobonichi Cousin.
It's worked well. At first I wondered if I'd manage to journal every single day, and also if I'd manage to fill up an A5 size page, but I have on both counts.
The Hobonichi is actually a planner rather than a journal and I did wonder how I'd fill up each section to make use of the whole book. There is a full page for each day of the year and this is where I do my journalling, but there are other sections too. I used the yearly section, which has just a line for each day of the year, to record my step count and I decided to use the weekly layouts to record reading, crafting and walks throughout the year.
The monthly sections never got used at all though.
I have to admit that writing in an A5 journal every single day of the year and filling up the whole page is quite time consuming, and as much as I've enjoyed using this Hobonichi, I've decided to go back to using my old journal, which is just an A4 undated book which I write in as and when. This book has been used since 2006 with years off here and there as I've tried out different journals, but in the end, I always return to it.
Who knows, after a year off writing every day I may try out a different journal again. Time will tell. Do you journal? What do you use to journal in? Do you write every single day or just when you have something to record?
