Does it really matter if I physically write in a journal or keep a digital one? What about video journals?

I don't think the type of media matters as long as you're keeping track of things. I think a video journal is a great idea.

I prefer digital. Can add more details later, add photos and videos. Can carry and access in multiple devices. Can take backup and secure. Can do search for contents.

I prefer writing because you focus on something real, physical and additionally you make the effort to take a pen and paper
