Ideally, we should all start learning a second language in elementary school/start of middle school. NOT in high school. Your brain is better wired for a new language when you are younger. But anyways, yes, you should learn as many languages as you can.
you speak as though everyone is monolingual. :/ I was raised bilingual in Vietnamese and English (although after not speaking Vietnamese for several years, I've lost the ability to speak it, and I never did probably learn how to read or write it), so any languages I learned would be considered my third, fourth, etc. language.
