Completely agree with @skieurope. I’d hardly call it a waste. I took 2 languages throughout high school with several friends taking 3. Some of them dropped one or all in college, others picked up even more in college and even more in grad school (one of my friends - who is doing his PhD in Classics at Harvard - is currently up to 9 foreign languages with some degree of proficiency: spanish, french, german, italian, latin, greek, hieroglyphics, aramaic, and sanskrit)
If the languages fit in with your goals/interests then they are absolutely not a waste but like @N’s mom said, it’s not going to make you look superior to other students who are only doing one language.
