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?
Another option for consideration is a tablet with a pencil stylus and palm rejection (personally, iPad works great for me). It doesn’t feel as nice as pen and paper ofc, but it strikes a nice middle ground since notes are highly editable, organisable and digitally stored. OneNote, as much as I despise Microsoft is really good for this.
There are also options for handwriting to digital transformation though you basically have to use english and have good handwriting that the algorithm can understand otherwise you will end up having to edit a lot.
I like to have a small pocketbook for important notes I want on hand and quickly (basically personal pocket guidelines in my case for the ED and a separate one for EMS), but I prefer taking lecture and study notes on my iPad in handwriting. Although I am slowly trying to create a digital version of my notes in a personal wikipedia style using Obsidian.
Also, not writing with a fountain pen is a disservice to yourself if you handwrite a lot.
