I learned to use a treadle sewing machine at school. Then a great aunt gave me her old one and I used that for years. When I first bought an electric sewing machine, I took the motor off it and attached it to the old treadle stand, with the leather drive belt to drive the machine, because I was so used to the treadle action and disliked the electric foot control. I use an ordinary electric machine now.
Apparently the way to teach a left-hander knitting is to get them to sit opposite you and mirror your actions. I didn't know this until after I'd taught left-handed DD2 to knit sitting beside me! She managed – by sheer determination not to be beaten by her older sister, I think.
Yes, a certain kind of patience is definitely an asset if you want to be a knitter.
