BJ is maybe the reason I found and hooked with obsidian now.
I heard the first time of BJ 2 or 1,5 years ago and was very interrested in that system. I tried it for several weeks but was lost after all because of my lack of self-discipline. I need a digital reminder, so I tried some digital tools and hoped to copy BJ in some way. But really nothing worked, like I wanted.
So I bought another noteblock to give the original BJ a new chance and failed again.
Some weeks ago I found obsidian and what should I say. I found more I was looking for.
I don’t think, I would use a BJ Plugin in Obsidian. That would be limitation. I really enjoy to take my notes and attach a task with the reminder Plugin. My index is the daily note with a modified daily agenda from the task plugin example page.
