Lack of knowledge in linguistics (or languages in general) is also what stopped my conlang project in its tracks.
Yeah I’ve had this issue too, but it hasn’t stopped me trying. I do try my best to understand the linguistics stuff enough to make sure my language is making sense, but it feels like a never-ending battle as there’s always more you can learn and add. I’m kinda fine with that though, and if it weren’t for conlanging I wouldn’t have realised I was into linguistics and started studying it at university.
Unfortunately I could never really get that into playing and practising solo and although I continued for a while regardless I eventually dropped my lessons, something I now kinda regret, but being part of an orchestra was always my favourite part of playing the violin.
