I’m planing on backpacking across Europe next year and I hate being the dipshit who only speaks one langue. I already have a small amount of german and spanish so those are the only two I’m interested in. I get the impression that outside of Spain spanish isn’t spoken much but I do plan on traveling south america at some point too so spanish is going to be needed eventually.
If you live in the US, Spanish will be eventually helpful to you in many ways, especially in political organizing. Spanish is one of the major languages of the colonized world and therefore an enormous amount of excellent politics is happening in Spanish. Learn Spanish.
