Languages (Score 1)

Depends where you are, of course, but over here in Europe having certificates for speaking languages can help a lot, even for anti-social loner nerds like me. The certificates show potential employers that you'll do hard work to gain new skills, and that you have skills that will always be useful somewhere. I might only use English professionally, but being able to share jokes with the locals in their own lingo gets lots of brownie points. I found, to my surprise, that as a software engineer, it's not difficult to pick up natural languages, maybe because the job involves using lots of (artificial) languages. Mind you, in some places, such as where I live & work now (Luxembourg), the locals use four languages, not one; people really need to speak a few of them not to come across as congenitally stupid. When I was 50, I was a monolingual English speaker. Less than a decade later, I have my marital arguments in French, tell rude jokes badly in Luxembourgish, fend off job ads in Dutch, & get the pizza I intended in German.
