How to pick a first instrument to learn?

Alright so I want to learn an instrument and there's a dilemma. My first choice is a piano and it's practically my dream instrument, it's my entire reason for wanting to learn an instrument.But I don't see myself having any access to a piano outside of lessons and I don't really see how I could learn without practice outside of lessons . So I'm leaning towards a violin since I could just buy one and practice whenever. I still REALLY want to learn piano though sooo.. Thoughts? Could u learn without practice and tbh even if I learned miraculously it might be a while (years) before I could get myself one . So that would mean I'd probably barely play. Thoughts???
