I kinda did it once before so I like to think I can do it again.
My arm got hurt pretty bad in a car crash when I was a kid, so basically had to retrain that muscle memory, it was a really frustrating feeling knowing that I could do something but NOT being able to do it.
Though my skills levels were not as high then as they are now because I was still a kid and learning I think it was still a pretty huge blow to my progress, as a lot of it was try drawing, get frustrated and quit for a year, trying drawing again cause I miss drawing, get frustrated and quit for a year, repeat process until I was at a level that didn't make me cry or destroy things in anger because it couldn't touch the quality of what I was able to do before.
I don't think I would draw a comic though, it's just a little bit too much skills sets you need for that that I would have to relearn, and I have arthritis now so I'm SUPPOSED to be working on comics a lot less than I do right now anyway. I'd probably just work towards being able to do stand alone illustrations of things I want to draw or just suddenly get the urge to illustrate, if I did go back to working I would probably put myself in a less demanding art field if anything.
I mean... that's my logical scenario anyway, in reality I would probably be like Miyazaki, retire, come back from retirement to makes this 1 last thing, retire, come back from retirement to make 1 last thing, retire, come back for this 1 thing this will be the last time for sure, retire, come back-
