I did this because I had been using diary apps and typing on computer and cell phone for too long that sometimes I don’t even remember how to write some of the words. So this is also a training for myself to re-collect writing in pen and paper.
I found this a better way to let the thoughts flow. Because when typing, I may misspelled by pressing the wrong key on the screen. The correction would take more time, and interrupt the flow of thoughts. Also I notice I am honest to myself when writing with a pen on paper. I tend to write what is correct instead of what is true when typing on the phone as it is usually for a message to others. And I tend to read back and edit, which is also a action to be correct instead of letting out the flow.
That’s my two cents for your reference.
