I feel strange about saying this but...
Since I'm full-day involved in dev world (2 years and a half), day to day I'm been getting an strange phobia to papper and pencil made documents, I'm don't know why but in University and work I feel uncomfortable making homework in a Notebook, I can spend a day front of mi Macbook and never will complain about it

I came really close to that. I mean, my calligraphy is really bad since I can remember. But it deteriorated in a huge way since I started to work with PCs daily.
It got to the point where it actually hurts to sit down and write for more than 5 minutes.

But I'm trying to get used to it again.
Usually, I like to draw and write a lot when coding because it helps me to understand the building blocks and interactions of the things I'm working on. But I kind of abandoned this a year ago.

Nothing beats the feeling of plain old writing with a pen on a nice piece of paper.

Even better if it's in a nice notebook.
