Really struck by what @neilhimself says in this interview about writing with fountain pens: "...the process of writing is always a process of trying to trick my brain into thinking that what I'm doing is not important. And I remember the joy of moving from the typewriter to the computer (which shows how old I am) and the great thing was I wasn't making paper dirty. And suddenly writing became easier. And then, I remember the point where I went 'You know, I think it's time to try writing on paper again because that feels less important.'
"But also I was getting fascinated by the way that medium creates sentences. I noticed that when I write on a computer I don't necessarily know where I'm going. I can make false starts and change things. If I'm writing in fountain pen I don't want to see lots of crossings out so I may actually think my way through to the end of the sentence without sort of approximat(ing). I'll get a little bit more precise."
I've had similar feelings. In the typewriter days I used to draft by hand in a throwaway spiral notebook, make notes in the margins, then do my final draft with the machine. First, word processing freed me, but for a long time it's been a trap of always being able to go back and revise. There's never a final draft. I almost embraced my fountain pen a couple years ago. Maybe I'll give it another shot. https://www.ruv.is/sjonvarp/spila/kiljan/32201/a005i3
