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 hope you decide to train your handwriting someday, being able to quickly write up a note or something is useful. But seeing how each person has unique hand writing it's also something one can be rather proud of. And then you have the calligraphy guys, I'll never be as good as them xd
