How I journal (and draw and stuff)

Even in some of my earliest memories I remember drawing or writing something. I wasn't some child prodigy, my drawing sucked back then and probably still does now and some of the things I was writing were literally copied from some weird books about animals and nature. But I still had the urge to write. It was inconsistent, sometimes going away for months and I think probably a year or two at some point but I always came back to it eventually.
At the end of 2016 I started writing Bringing Back Rain, a truly awful book full of cliches and problematic plot points. I can say that even though I only finished it early this year and even while writing it I realised it had it's problems. But the key part of this is that I finished it. I wrote a lot during 2017, most of it useless but it still furthered my writing.
I also started a journal. I've started diaries and notebooks a lot but I always had a specific use for them in mind and usually wanted them to look perfect. When I started writing this time though, I picked up a notebook I didn't even like that much and just wrote whatever I wanted - from fun scenes to to-do list, character and plot plans, poetry and diary things. And I filled up the whole thing in a year.
There are lot's of videos on Youtube giving suggestions what to write in your notebooks. My opinion on that is: everything. No one has to see it so why limit yourself? Everyone has weird thoughts or wants to remember something and that's exactly what you should write down.
If it sucks, you can leave it or rip out the page. And if you're not happy with you're notebook anymore you don't have to finish it. Or you do but make a title page in the middle to give yourself a fresh start.
The same thing goes for sketchbooks. Ideally I'd combine the two but I want to finish my current sketchbook before doing that.
I don't have one reason for journalling. I like how I can look back on my thoughts, writing somewhere other than my laptop, sketching out unfinished ideas or writing poetry because it feels so much better to do that on paper.
If you want to see an artistic masterpiece on the topic watch SoSonia's video "Why I journal" on the youtube channel Soulpancake. I assure you, after watching it you will want to do something creative.
Do you journal? If so, why? And what do you like about it?
