Should I keep trying to learn a language?

I've been struggling with this for some time, if one of you has any advice I would really appreciate it.

I've always wanted to learn another language. I grew up in America, raised by Arabic speaking immigrants. One parent passed away, and my other parent avoided speaking arabic to me out of concern that it would affect my studies (a 1st grade teacher complained to her that my older sibling was speaking arabic by accident, so my parent worried it was conflicting with her learning—they realize now how silly that was in hindsight). As a result my arabic is pretty bad.

In highschool, I learned German because typical mid tier white people school in america gives you only German, French, Spanish, and at shitty schools like the one I went to you are lucky to have "exotic" options like Russian and Latin lol.

I loved learning German, in fact as I write this I am in Vienna, appreciating the beauty and culture and dabbling in trying my German skills from highschool, its what made me write this post out.

I just never could make language learning stick after highschool where it was more or less compulsory. "If you want to get into a good college you need a language!" was the advice we were all given, and I liked German and it was free so I stuck with it. But now I find myself lacking in motivation or willpower or whatever.

I have no cultural ties or reason to learn German really. If I could choose a language to instantly reach max fluency in, I would pick Arabic so I could speak in my parent's native tongue. Arabic is even harder to learn though.

What confounds me is how often throughout the years I keep wanting to learn Arabic and then how many times I've given up or its just fallen off the wayside and been deprioritized. It makes me wonder, and its why I've come here to ask—Is this a motivation/willpower problem or do I just not have a strong enough reason to acquire another language?

Am I just lazy and I need to push through, or is Arabic just not valuable enough to bother learning? Because in America I speak to literally NO arabic speakers except my parent. I don't have cultural ties to Arab things. I don't listen to the music, but when my parent plays it I do enjoy listening here and there. Don't watch arabic shows. Don't really feel like I identify with Arab things, specifically the levant since that's where family comes from. It's kind of just what happens when you are born in a new country like the united states and you never visit the old country (its war torn so my parent says its not safe to go).

So, does that mean its just silly for me to try? Does this mean I should abandon this fantasy? If this is the case, I don't get why I keep coming back to fantasizing about being a bilingual. There's clearly still some part of me that really wishes I could speak another language. What do you think I should do?

Thank you for taking the time to read my post.

Edit: I should probably add that I have not tried much since school: Duolingo, at one point trying to get a language tutor through an app, but I gave up pretty quick on that when I returned to grad school. I think now I am in a better place to try again, but I want to put my best foot forward and stop giving up so easily.
