When talking to my advanced students, I often compare learning a language to swimming against the current: if you stop swimming you go backwards. Learning a language is a life-long pursuit.
In a metaphorical sense, swimming against the current means going against prevailing opinion or thought, as in I'm voting for him even if that is swimming against the current. Shakespeare used a similar metaphor in Henry IV "You must now speak Sir John Falstaff fair, which swims against your stream." You can also say swim against the stream or tide. The antonym is swim with the tide.

Guess if the following words entered the English language in the 60s, 70s or 80s.
