With so much note taking apps nowadays, I can’t understand why does anyone still write notes with pen and paper. You need to bring the notepad, book or that paper to retrieve that information, and most of the time you don’t have it in hand. While my phone almost always reachable and you carry when you go out. For those still like to do handwriting, there’s many app does that and they can even convert it to text notes.
So, if you still write notes with pen and paper, why?
I do both, and it’s heavily dependent on what the purpose of the note is for.
I keep a yellow legal pad and mechanical pen. Stuff that goes on the pad are usually the ultimate in throwaway notes. Scribbles that are wholly transitory.
Then I have a digital note management system (Obsidian.md) and use it to maintain a personal journal and Zettelkasten.
Some yellow pad notes might flow into Obsidian, but not always.
