I do have a primary notebook, and by default, it is indeed a “Dirt Notebook.” It is my own way, and I’m sure things will continue to evolve. I use that single/primary notebook for everything, everyday use. I have settled on a standard A7 notebook making it easy for me to buy just that.[1]

My writing style is ‘harnessed’ by a simplified Bullet Journal method,[2] complete with diagrams, writing on the sides, sometimes vertical, and everything else in between. However, the interesting thing is, my notes are still one of those that gets shared by other people in the same meeting. I tend to draw out everyone’s speech and ideas into visuals that make me understand better.

I also start writing from the last page of the notebook too, to maintain a running list of TODO/TASK items.

When a page is parsed or transferred or no longer valid, I mark that page as ‘archived.’ This is usually done weekly or whenever I feel like it with the same simple fountain pen or a colored marker if I find it nearby. This way, I know which page I never need to look back at and which ones need to be re-checked later.

Individual pages sometimes contain TODO/TASK too. This is where the Bullet Journal method comes in to finish it off.

For contents that are useful for future references, such as resources of knowledge or ideas or a journal entry, I transfer them to my digital notes, the physical journal, and the commonplace book. [3]

These might seem complex, but after a while, they have become muscle memory for me. If you want to start off today, constrain yourself with something "un-dirty" like the Cornell Note Taking System[4] to build up a habit.

I’m including links to some of my personal blog’s articles (not very popular around here), but it makes sense with the above notes I just wrote.

Edit/Addendum: I think it is only fair to confess that I am inspired by the note-taking style of Leonardo da Vinci depicted and dramatized in movies, and TVs. I’m just a low-level copier and thief of the methods of such a great person.
