Steve Kaufmann (aka The Linguist) argues the point that language learning is more than a task to be completed wholly, a skill to be learned to a specific point of satisfaction or superlative. As he says, “it’s not about performance”:

Athletes compete to see who can run faster, or jump higher, or execute their moves with more precision, or score more goals. Athletes train in order to improve their performance. Learning languages is different. It is, for me, about communicating and enjoying another culture. In fact the learning process, itself, is enjoyable, regardless of the outcome, regardless of the performance. It is possible to enjoy languages without performing at all, without speaking. And when we speak we do not want to be judged, or at least I do not.

I often get comments on my foreign language youtube videos along the lines of:

“your Portuguese is not very good, don’t you care?”
” your Japanese sounds a little American, you should work on your accent.”
” you made a mistake in your Russian.”

Well, I don’t care. I am not in competition with native speakers, nor with other non-native learners of any language. If my mistakes are pointed out, it is likely that I will make the same mistake the next time. I know what gives me trouble in these languages. I try to pay attention to these things when I listen, read or speak. But I know that I will continue to make mistakes and will only gradually improve.

More here. There is further discussion in the comments section of that post.
