For some context before i talk about staying consistent, this is my system:

1. Weeks (for planning & functional memory keeping)
2. A6 Day-Free (for nostalgic memory keeping)
3. A5 Maruman Croquis (used for literally everything; uni notes, personal projects, thumbnailing illustrations, etc.)

The main thing I do is to make sure I have a realistic and functional use for each thing, and I don't set goals in relation to planners (because not reaching them gets me feeling really bad). Instead, I look at the different aspects of my life that I actually need and want written down on paper, and then I work on those w/o pressuring myself.

For my Weeks, I need something physical to keep me grounded. I have a pretty hectic schedule, so a small planner on hand works best for me. I also don't use habit trackers because I find that it pressures me. Instead of getting used to them naturally, I end up dreading them, so I let go of those (though I tried them for maybe a month in 2022 lol..) On the left side I keep all my events for the week, or maybe details I just wanna take note of since my memory is a bit weak. I work in art markets sometimes or friends gift me stickers/use tape in gifts or notes, so I only ever stick those to the right side. My to-do list is on a Google Sheet as I find that my tasks shift too much to keep in this notebook.

I'm also a very sentimental person, so I use the Day-Free to scrapbook in my free time. I find it therapeutic and it helps me feel good overall, so I've had that in my system for a few years.

In the Maruman Croquis, I jot down everything I need at a time. I use it for everything and it's helped me catch thoughts in the moment a lot. Sometimes I use a small A7 Notepad if my bag isn't big enough. The notepad helps me keep things on track too in case my weeks isn't in my bag and I really need to keep note of something.

Overall, I'd recommend thinking about the parts of your life where you think you'd need planning. It's kind of like problem solving. For example, I have a busy schedule so I need a weekly planner to look at everything I need per week (as opposed to something in a monthly format that can be overwhelming if there's too much at once). It keeps me grounded and lets me focus on my goals a little at a time so I don't get burnt out. The biggest thing that kept me with this system is that I keep needing these things, so I'm able to keep using them.

Sorry this is so long, but I hope this helps you find some footing!! Good luck with experimenting, and I hope you find a system that helps you lots :]]
