I have a writing callus on my right digitus medius (middle finger - FYI I totally had to Google that, I'm a little bit in love with Latin).
I got it when I was at uni studying law. It developed into a much bigger callus during my final year, when I was writing my honours thesis. A 28 thousand word epic on corporate manslaughter. Would you believe me if I told you I had fun writing it?
I did. I'm a total nerd.
The research part of it I did by hand. With 2 thick A4 notebooks and countless pens. I wrote out my observations by hand and left large margins for summarising later. It made the actual writing process much quicker in the end (if you ever need to write a thesis) even though it takes quite a lot longer to do all the reading at the initial stages.
My thesis took a year in total to complete. I had a part time job, and was finishing off the last 5 subjects of my degree - all at the same time.
I was a crazy person that year. So distracted by law that everything peripheral dropped away for a while. I became a completely absent minded, sleep deprived, corporate law obsessed individual. It was hilariously fun (for me anyway, not sure about everyone else involved).
By the time I was finished and after I handed the epic in, I was so proud of that callus, and a little bit devo at the idea it would heal (no chance of that it's never gone away).
So you can imagine my delight that as a lawyer (especially in my current job) - we still use pencils and pens and paper. Some don't, but I definitely do. Flicking through a large document is tricky on a computer screen. I won't print something if I don't have to (love trees too much for that), but if someone sends me a contract to read in hard copy, I'll sit at my desk all day with a pencil and mark it up by hand.
At times, my computer sits idling for 70% of the day, which I reckon is pretty fantastic. If I hear the email boop I'll check it's not urgent. Otherwise I can spend hours just doing my work by hand. Then every few weeks I carefully sharpen all my pencils.
I have lots and lots (*whispers and lots) of favourite things, and pencils is most definitely one of them. Especially coloured pencils but I'm not sure my boss would appreciate if I coloured in all our leases.
