Surely the grind of learning to play a violin would be far worse if you disliked violins in the first place, right? If you force somebody who hates violins to practice playing one for hours a day, the grind would be intolerable and they'd probably hate their life. The people most likely to find the grind tolerable are the people who really want it.
> It's only a 'grind' if you don't enjoy the process though, right?
I'd summarize my answer as "no, it's still a 'grind'." To answer your followup, "yes, it can be even worse if you hate the basic act."
On a meta level: life sucks and involves hardship. There's value in grinding on things you hate. If you've only succeeded at things that you love, your success is quite likely fragile. Resiliency is developed by accepting, and grinding, your way to success at something you hate.
