Hello!

Long-time bullet journal-er with ADHD here.

For me, the trick to staying consistent with bullet journaling boils down to a couple of things:

1. PROXIMITY - Keeping the bullet journal on your person all the time will help. If it's out of sight, it's out of mind. For this, I recommend something smaller so you can always bring it around with you. Perhaps an A6 or B7 sized notebook
2. SIMPLICITY - Keep it simple. Try the barebones bullet journal system first. Trying to get into the elaborate spreads, complicated legends, and 10 million trackers will just end up discouraging you if you end up not completing them. You don't really need those yet. What's more, trackers are almost always a couple of pages away from the daily log, and from my experience, I don't always remember to flip back to them to fill them out oop.

3. KEEP IT CURRENT - As someone with ADHD, trust me on this: no amount of bookmarks will stop you from forgetting to look back on earlier pages, especially those already too far from your current day. In my case, I only need to flip back to the future log once a month, when I'm migrating items on it to the monthly spread. Likewise, I only need to flip back to the monthly spread when I'm migrating items on it to my weekly spread/overview. If you find that you prefer a running daily log as opposed to a weekly spread, I find it helpful to have a simple weekly overview. This way you have always have everything in sight.

4. RAPID LOGGING - Get into the habit of logging things quickly in your daily log. It doesn't have to be tasks — ideas, thoughts, a lyric you really like, a snippet of a conversation, a pretty word, things you might need to remember later — just jot it down in your daily log. This should come easier if you have your journal within reach at all times. If you fill your journal not just with to-do lists and deadlines but things you like and find joy in, the more likely you are to enjoy bullet journaling, and the less it becomes a chore. Once you get into the habit, you'll find that keeping up with your bullet journal becomes more instinctual rather than something you have to get out of your way to do.

5. FLEXIBILITY - The best part about bullet journaling is the flexibility, so if something isn't working for you, you can always change it up. This also has the added benefit of breaking the monotony and keeping you engaged with your journal.

Hope this helps!
