It all depends, for example, I currently live in a country where 0.5 of 10 citizens can speak english, not proper english but they try, I dont consider myself as an english speaker but I've learn a lot and I can actually say that I CAN speak english properly, everybody tells me that it is going to open many doors for me, job offers, girls will like me as soon as I start talking and stuff like that, I could really use that as an inspiration for my self person, however it will benefit you depending on the use you give to it, if you're learning because you wanna get a girlfriend go ahead and do it if you want but that is not a proper motive to learn, we gotta learn because we love it and we're somehow going to make a living out of it, at least that is what I think about that so yes, it benefits you a lot in many ways.
