Italia I was thinking of that bujo thread you linked to, and I couldn't find it - thank you for linking to it, it's a good thread as it discusses loads of different approaches to journalling.
OP, yes I feel the need to write every day. I just use my journal for everything really - so I just divide it up as I go into daily tasks, reminders, events, etc. So it's really a blank notebook and I put in what I want.
But I also use it for goals, things I want to try, etc. I find my brain doesn't get so "clogged" when I have put stuff down on paper, like if it's on the page, it's taken care of because I don't have to give mental energy to thinking about it again. I might have to do the actual task itself, but I don't have it constantly popping into my head etc and worrying that I have to remember.
Also I like to have goals and plans written down as things to look forward to/stay focused on/stay positive about.
It's helped my mental health and quality of life massively. It sounds totally dramatic to say that, but it really has.
Wishing you all the best
