But, respectfully, this thread was OP asking if self taught ASL is a hook- and it just isn’t. It’s a nice thing, like so many nice things kids do. No particular pull. Not a great challenge, she’s not working in the deaf community. And it may not relate to her major. (Eg, if she wants an education major.) And it’s not community service.
"Ivy League material " is a whole lot more than some nice thing(s) you like to ro. and OP needs to learn a lit more about what that is.
