Meanwhile out there in the real world, if you specifically want to get a job that requires you to speak Chinese, you are going to have to attend a course in Chinese, to actually learn Chinese. Unless you are actually native Chinese in which case you won't have to attend that course.

Though depending on the situation I might still find that it's useful to attend the course, so I can get certification as having gone through the course, which in the real world might be of more value than speaking Chinese without that certification.

And these sorts of certification-based (as opposed to skill-based) considerations apply to most disciplines as well.

And, of course, the fact that I'm applying for this job, which requires Chinese, is itself a choice I'm making, and we can ask why I'm making that choice, and to what extent my motives are status-seeking vs. truth-seeking vs. improvements-in-the-world-seeking vs. something else.

Conversely, if I am entirely uninterested in certification and I really am solely interested in learning Chinese for the intrinsic value of learning Chinese, I might find it's more useful not to attend a course, but instead study Chinese on my own (e.g. via online materials and spending my afternoons playing Mahjong in Chinatown).
