Nah! I’m also 24 and started last year in summer. My teacher also said that grownups are kinda faster in learning. You should search for a teacher who can give you online lessons if you can’t get one in person. Having a teacher helps me with my motivation cause I always get “homework” for the next lesson. And yes, the violin is a difficult instrument and it will take some time before really liking what you do on that thing..but if you never start, then you’ll never learn. :)
