No! Learning more languages does not make you more valuable, contrary to popular belief. In fact, I argue in my book Pewep and the 7 Laws of Internet Marketing that those languages will use up too much space in your brain. When you get older, your brain will have to sort through the different languages in order to find the correct word. I recommend you forget those languages at once.
