if you can get one of English, Chinese or Japanese at native level, and the other two at business level, then you've got a road paved in gold ahead of you

why bother with a 4th language, and why bother going fluent.

if English is your native language then study Japanese and Chinese, major in Japanese and minor in Chinese and done. Being a native English speaker is worth more here than any paper saying you know the language. Dutch is such a useless language here... you might get one job every 3 years to translate a label on a towel or something.

Plenty of work for translators and interpreters etc
